Question

The “Compton effect” showed

that light behaves like a wave
how an experiment can mislead
the wave nature of light
the particle nature of light

Answer 1

the particle nature of light

Step-by-step explanation:

As we know that by the formula of Compton Effect we have

`\lambda' - \lambda = (h)/(mc)(1 - cos\theta)`

here in this formula we will say that when light of some given wavelength
`\lambda` incident on a particle then after deviating from the particle the light will change its direction by some angle
`\theta`.

And the wavelength of the particle will also changed to some different value as
`\lambda'`

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

Answer 2

The answer is the last choice, the particle nature of light. The compton effect showed that a charged electron scatters the photon results in decreased energy but increase in wavelength.
