Answer:
Wavelength, [tex]\lambda=8.57\times 10^{-8}\ m[/tex]
Explanation:
Given that,
Frequency, [tex]f=3.5\times 10^{15}\ Hz[/tex]
We need to find the wavelength of a photon of light. The relation between frequency and wavelength is as follows :
[tex]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[/tex]
So, the wavelength of the light is [tex]8.57\times 10^{-8}\ m[/tex].
