Question

If a photon has velocity c and frequency v, then which of the following represents its wavelength?

Answer 1

Here's your answer

velocity, c = frequency * wavelength
-: wavelength =velocity /frequency

Answer 2

Answer:

Option c is correct.

Explanation:

Options missing in question, they are given below

(a) hv/c2 (b) hv (c) hc/E (d) hv/c

Explanation:

The energy of the photon is given as

$E=\frac{hc}{\lambda}$

Here h is the plank`s constant c is the speed of the light and $\lambda$ is the wavelength of a photon.

Photon energy can also write,

$\lambda =\frac{hc}{E}$

Thus, wavelength is $\lambda =\frac{hc}{E}$.
