Explanation:

Answer 2

Answer:

Electromagnetic Theory:-

This theory was given by Clark Maxwell

Main points are:-

i) When an electrically charged particle moves under acceleration, alternating electrical and magnetic fields are produced and transmitted. These fields are transmitted in the form of waves. These waves are called electromagnetic waves or electromagnetic radiations

ii) Energy emitted from any source continuously the form of radiations & is called radiant energy.

iii) The radiation consists of electric & magnetic fields oscillating perpendicular to each other & both perpendicular to direction of propagation of radiation.

iv) The radiation possesses wave character & travel with the speed of light (3 X 108 m/s)

v) These waves do not require any meteoric medium for propagation.

BUT !!

Classical physics said that each frequency of vibration should have the same energy. This means that, there should be no limit to the energy of the light produced by the electrons vibrating at high frequencies. WRONG!! Experimentally, the blackbody spectrum always becomes smaller.

One experimental phenomenon that could not be adequately explained by classical physics was black-body radiation. Hot objects emit electromagnetic radiation. The burners on most electric stoves glow red at their highest setting. If we take a piece of metal and heat it in a flame, it begins to glow, dark red at first, then perhaps white or even blue if the temperature is high enough.

Hope it will help :)
