The wavelength of light that has a frequency of 1.20 × 1013 s-1 is ________ m.
Given that
Frequency of the given light = f= 1.20 × 1013 s-1
Find out
We need to find out the wavelength (λ) of the given light.
Formula
The relationship between frequency and wavelength for an electromagnetic wave is given by
c=f λ———–(i)
Where,
c is the velocity of light
f is the frequency of light
λ is the wavelength of the light
Solution
To find the wavelength of the given light we will substitute the known values in equation (i) we get,
c= f λ
c= 3 X 108 ms-1
f= 1.20 × 1013 s-1
λ we need to find out
Therefore the equation becomes
3 X 108= 1.20 × 1013 x λ
λ= 3 X 108 / 1.20 × 1013
= 2.5 x 1o-5m
Hence, The wavelength of light that has a frequency of 1.20 × 1013 s-1 is 2.5 x 1o-5m
