A cellular telephone transmits electromagnetic waves at a frequency of 835 MHz. What is the wavelength of these waves?
A)0.0146 m
B)0.359 m
C)0.842 m
D)1.62 m
E)2.47 m

Question

Quizplus · Accepted Answer

The wavelength (λ) can be calculated using the formula λ = c/f, where c is the speed of light (approximately 3 x 10^8 m/s) and f is the frequency. For 835 MHz (which is 835 x 10^6 Hz), the wavelength is approximately 0.359 m.
