In classical electrodynamics energy of a wave is proportional to its intensity , this theory fails when Hertz did experiment on photoelectric effect. Is my statement is correct? If not correct me.

But I thought Einstein proposed quantisatiion to explain the effect. Why does intense white light not create electron emission?George Jones said:Quantization of the electromagnetic is consistent with the photoelectric effect, but it is not necessary to explain the photoelectric effect, .

PeterDonis said:What do you mean by "intensity"? The correct mathematical statement is that the energy of a classical EM wave is proportional to the square of its amplitude.
George Jones said:This is explained in the text that I referenced, which probably is unavailable to you. See also the video below (between times 27:30 and 30:23), by Alain Aspect, who, in my opinion, should be a Nobel Laureate.
The energy of a wave is the amount of energy that is carried by the wave as it travels through a medium. It is directly related to the frequency and amplitude of the wave, with higher frequencies and amplitudes corresponding to higher energy waves.
The energy of a wave can be calculated using the formula E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the wave. This formula is known as the Planck-Einstein relation and is used to calculate the energy of electromagnetic waves.
The photoelectric effect is the phenomenon in which a material, typically a metal, emits electrons when exposed to light of a certain frequency. This effect was first observed and studied by Albert Einstein and is a crucial concept in understanding the relationship between light and matter.
The energy of a wave is directly related to the photoelectric effect. In order for the photoelectric effect to occur, the light must have a minimum frequency, known as the threshold frequency. This frequency is directly related to the energy of the wave, with higher energy waves being able to cause the photoelectric effect.
Yes, it is correct to say that increasing the amplitude of a wave will increase its energy. This is because the amplitude of a wave is directly proportional to its energy, with higher amplitudes corresponding to higher energy waves. However, it is important to note that changing the amplitude alone will not change the frequency of the wave, which also affects its energy.
