The wavelength of light that has a frequency of 1.20 1013s-1 is __________ m.

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
