Calculate the ionisation energy of sodium in k-J mol-1. In another experiment, remaining sample was irradiated with a light of wavelength 6 0 0 A ˚ , when all the electrons are removed from the surface. Black body radiation and Photoelectric effect. When radiations with certain minimum frequency ( νo) strike the surface of a metal, the electrons are ejected from the surface of the metal. This document is highly rated by … In 1900, Max Planck established the Planck's Quantum Theory that states that radiant energy, such as light and heat, is … The behavior of electromagnetic radiation depends on its wavelength. Class 10 Class 12. The different types of electromagnetic radiations differ only in their wavelength and hence frequency. Atom is made of electron, proton and neutrons. It is observed that the kinetic energy of the ejected electron depends upon the frequency of the incident light but not on the intensity of the light radiation. The electron will be detached from the metal atom only if the energy of the photon is sufficient to overcome the force of attraction of the electron by the nucleus.That is why photoelectrons are ejected only when the incident light has a certain minimum frequency (threshold frequency ν. why is the graph of intensity-waveleng from Chemistry Structure of Atom Class 11 CBSE Overview. If the substance being heated is a black body (which is a perfect absorber and perfect radiator of energy ie. This is possible only when you have the best CBSE Class 11 Chemistry study material and a smart preparation plan. It is represented by ν (nu) and is expressed in hertz(Hz) or cycles/second or sec-1. Max Planck in 1900, put forward a theory known after his name as Planck’s Quantum theory. Wave nature of electromagnetic radiation is characterized by its following three properties – … 3)The number of photoelectrons ejected is proportional to the intensity of incident radiation. It is represented by c and is expressed in cm/sec or m/sec. Candidates who are ambitious to qualify the CBSE Class 11 Chemistry with good score can check this article for Notes. Electromagnetic radiation is commonly referred to as "light", EM, EMR, or electromagnetic waves. ... Dual Behaviour of Electromagnetic Radiation. ... What is the wavelength of electromagnetic radiation broadcast by the radio station? NCERT Exemplar Class 11 Chemistry is very important resource for students preparing for XI Board Examination. b) If, deuterons and alpha particle are accelerated through same potential, find the ratio of the associated de-Broglie wavelengths of two. 3)When the intensity of light is increased, more electrons are ejected but the energies of these electrons are not altered. Since most of the light present in this universe is invisible to the naked eye, starting from x-rays, radio waves to gamma rays. Ans: The energy which is produced by the oscillating body and which is propagated in the form of waves through space is called electromagnetic radiation. Fluids such as these may be assumed to consist of a huge number of particles” composed of a massive number of molecules each. The electron will be detached from the metal atom only if the energy of the photon is sufficient to overcome the force of attraction of the electron by the nucleus.That is why photoelectrons are ejected only when the incident light has a certain minimum frequency (threshold frequency ν0). 11 students and has been viewed 3496 times of emitted electron is waves!

It is a 3D form of the wave equation. It could not explain Maxwell's electromagnetic radiation property. 3)The total amount of energy emitted or absorbed by a body will be some whole number quanta. Class 10 Class 12. He performed the experiment in a discharge tube which is a cylindrical hard glass tube about 60 cm in length. This is called speed of light. The radiations are called electromagnetic radiations or electromagnetic waves. Amplitude of a wave is the height of the crest or the depth of the trough. A general equation relating the speed of light, frequency, and wavelength of electromagnetic radiation is given below: Apart from frequency and wavelength, some other parameters are also used to categorize the electromagnetic radiation. 4 mins.

Calculate the ionisation energy of sodium in k-J mol-1. In another experiment, remaining sample was irradiated with a light of wavelength 6 0 0 A ˚ , when all the electrons are removed from the surface. Black body radiation and Photoelectric effect. When radiations with certain minimum frequency ( νo) strike the surface of a metal, the electrons are ejected from the surface of the metal. This document is highly rated by … In 1900, Max Planck established the Planck's Quantum Theory that states that radiant energy, such as light and heat, is … The behavior of electromagnetic radiation depends on its wavelength. Class 10 Class 12. The different types of electromagnetic radiations differ only in their wavelength and hence frequency. Atom is made of electron, proton and neutrons. It is observed that the kinetic energy of the ejected electron depends upon the frequency of the incident light but not on the intensity of the light radiation. The electron will be detached from the metal atom only if the energy of the photon is sufficient to overcome the force of attraction of the electron by the nucleus.That is why photoelectrons are ejected only when the incident light has a certain minimum frequency (threshold frequency ν. why is the graph of intensity-waveleng from Chemistry Structure of Atom Class 11 CBSE Overview. If the substance being heated is a black body (which is a perfect absorber and perfect radiator of energy ie. This is possible only when you have the best CBSE Class 11 Chemistry study material and a smart preparation plan. It is represented by ν (nu) and is expressed in hertz(Hz) or cycles/second or sec-1. Max Planck in 1900, put forward a theory known after his name as Planck’s Quantum theory. Wave nature of electromagnetic radiation is characterized by its following three properties – … 3)The number of photoelectrons ejected is proportional to the intensity of incident radiation. It is represented by c and is expressed in cm/sec or m/sec. Candidates who are ambitious to qualify the CBSE Class 11 Chemistry with good score can check this article for Notes. Electromagnetic radiation is commonly referred to as "light", EM, EMR, or electromagnetic waves. ... Dual Behaviour of Electromagnetic Radiation. ... What is the wavelength of electromagnetic radiation broadcast by the radio station? NCERT Exemplar Class 11 Chemistry is very important resource for students preparing for XI Board Examination. b) If, deuterons and alpha particle are accelerated through same potential, find the ratio of the associated de-Broglie wavelengths of two. 3)When the intensity of light is increased, more electrons are ejected but the energies of these electrons are not altered. Since most of the light present in this universe is invisible to the naked eye, starting from x-rays, radio waves to gamma rays. Ans: The energy which is produced by the oscillating body and which is propagated in the form of waves through space is called electromagnetic radiation. Fluids such as these may be assumed to consist of a huge number of particles” composed of a massive number of molecules each. The electron will be detached from the metal atom only if the energy of the photon is sufficient to overcome the force of attraction of the electron by the nucleus.That is why photoelectrons are ejected only when the incident light has a certain minimum frequency (threshold frequency ν0). 11 students and has been viewed 3496 times of emitted electron is waves!
