What is the wavelength of 200 MHz television EM waves? (c = 3 × 10⁸ m/s) A) 9 km B) 10 m C) 1.5 m D) 3 m

Question

Quizplus · Accepted Answer

The formula for calculating wavelength is:

wavelength = speed of light / frequency

Given, 
frequency = 200 MHz = 200 x 10^6 Hz 
speed of light = 3 x 10^8 m/s

Using the above formula,

wavelength = (3 x 10^8 m/s) / (200 x 10^6 Hz) 
wavelength = 1.5 m

Therefore, the wavelength of 200 MHz television EM waves is 1.5 m. The correct choice is C).
