It is determined that a certain wave of infrared light has a wavelength of 8.45 mm. Given that c=2.99 ×108 m/s, what is the frequency of this infrared wave? (Round your answer to three significant figures.) Hz

The frequency of infrared wave is 35.385 GHz

Explanation:

Given data:

Wavelength of infrared light = 8.45 mm = 8.45 x m

Velocity of infrared light = 2.99 x m/s

To find: frequency of the infrared wave = ?

We know that the wavelength and frequency are inversely proportional and the formula to derive frequency with velocity and wavelength is:

c = μλ, where

c is velocity of light

μ is frequency of light

λ is wavelength of light

Hence the frequency of light  μ = c/λ

                                                     =

                                                     = x

                                                     =  35.385  x   Hz   (since 1 = 1 Hz)

                                                     = 35.385 GHz

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.
