Question

What is the wavelength of a 4.34x10^15/s wave?

Answer 1

6.9 × 10²² m

Step-by-step explanation:

Data Given:

Frequency of wave = 4.34 ₓ 10⁻¹⁵s⁻¹

wavelength = ?

Solution:

Formula used

c = λν

Where

c = speed of light = 3 × 10⁸ ms⁻¹

λ = Wavelength

ν = frequency

As we have to find out wavelength we have to rearrange above equation

λ = c /ν . . . . . . . .(1)

Put values in above equation 1

λ = 3 × 10⁸ ms⁻¹ / 4.34 ₓ 10⁻¹⁵s⁻¹

λ = 6.9 × 10²² m
