Answer:
the particle nature of light
Explanation:
As we know that by the formula of Compton Effect we have
[tex]\lambda' - \lambda = \frac{h}{mc}(1 - cos\theta)[/tex]
here in this formula we will say that when light of some given wavelength [tex]\lambda[/tex] incident on a particle then after deviating from the particle the light will change its direction by some angle [tex]\theta[/tex].
And the wavelength of the particle will also changed to some different value as [tex]\lambda'[/tex]
so here as per particle theory we will use the theory of momentum conservation as per which light of given momentum when hit a particle then it will transfer it momentum to the particle and deviated by some lesser momentum.
Due to decrease in momentum the change in wavelength of light is given by above formula
so this verify the particle nature of light
