The photon has a wavelength of 5.56xx10^12 m5.56×1012m

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")/((5.4xx10^-5)/cancel"s")

lambda = 5.56xx10^12 m
