Question

Calculate the wavelength of a photon of light having a frequency of 3.50 x 1015 Hz.

Answer 1

Answer:

Wavelength, $\lambda=8.57\times 10^{-8}\ m$

Explanation:

Given that,

Frequency, $f=3.5\times 10^{15}\ Hz$

We need to find the wavelength of a photon of light. The relation between frequency and wavelength is as follows :

$c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{3.5\times 10^{15}}\\\\\lambda=8.57\times 10^{-8}\ m$

So, the wavelength of the light is $8.57\times 10^{-8}\ m$.
