Q. Determine the wavelength of light wave?

Ans. The frequency of an infrared wave is 2.07 x 10¹⁴Hz. What is the wavelength?

c = λv

Since we know the speed of light we can just solve for wavelength.

Notice how the units cancel leaving us with units of m, for wavelength.

Remember to round off to 3 significant digits:

Notice that wavelength is a very small number because the frequency was so big.
