lambda = 4.75xx10^4 mλ=4.75×104m

Explanation:

To answer this question, we can use the wave equation formula:

Where lamdaλ is the wavelength and it has units of meters. cc is the speed of light and it has a value of 3.0xx10^8 m/s3.0×108ms. ff represents the frequency and it has units of Hertz or reciprocal seconds (1/s1s).

We know the frequency, ff and the speed of light since that is a constant. All we have to do is plug in the known values and solve for lambdaλ:

lambda = (3.0xx10^8 m/cancel"s")/((6.21xx1018)/cancel"s")

lambda = (3.0xx10^8 m/cancel"s")/(6321.78/cancel"s")

lambda = 4.75xx10^4 m
