Quizplus · Accepted Answer

The formula for calculating frequency is wavelength (λ) multiplied by speed of light (c), divided by the wavelength. So, f = c/λ. Plugging in the given wavelength of 2.81 m and the speed of light (3 x 10^8 m/s), we get f = (3 x 10^8)/(2.81) = 106.8 MHz. Therefore, the answer is B.

A Radio Station's Operating Frequency Has a Wavelength of 2
