Answer:
13.6 m
Step-by-step explanation:
To find the wavelength, you need to use the following equation:
c = λ · f
In this equation,
-----> c = speed of light (3.0 x 10⁸ m/s)
-----> λ = wavelength (m)
-----> f = frequency (Hz)
You can plug the given values (speed of light and frequency) into the equation and then solve for "λ".
c = λ · f <----- Equation
(3.0 x 10⁸ m/s) = λ · (2.20 x 10⁷ Hz) <----- Insert values
13.6 = λ <----- Divide both sides by 2.20 x 10⁷
