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

6.9 × 10²² m

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

i believe the answer is a.
