Question

The frequency of oscillation of the wave emit- ted by an FM radio station is 88.7 MHz.
Find the period of vibration. Radio waves travel at a speed of light; 3 × 108 m/s.
Answer in units of ns.

Answer 1

Explanation:

Period = 1 / frequency

T = 1 / (88.7×10⁶ Hz)

T = 11.3×10⁻⁹ s

T = 11.3 ns
