I have a physics question

Question

Explain how the photoelectric effect supports a particle model of electromagnetic radiation. Evaluate the idea that radiation frequency and intensity highlight how the wave model is inadequate to explain the photoelectric effect

Answer 1

The Photoelectric effect support the particle model because due to effect depended on the frequency and not the intensity of light ,the particles have certain energy that create the effect not the absorption of wave.

Light can be though of a stream of particles(photons). In order to emits the electronics the metal must be struck by photon of light that contains quantum of energy.

Planck's constant quantum theory (electronic magnetic energy occur in the little "packets" called photons.) Energy of photon = hf

h= 6.63*10^-34 and photon frequency.

1. Now Photoelectric effect arise when photons of light strike on the surface transfer to the electronics.
2. These energized electronics overcome their attraction for nucleus but electron can escape only if the photon provide the energy .
3. Higher is the frequency photons more is the energetic photons.
