Question

A radio station broadcasts at 80 MHz.How long does it take for this radio signal to travel a distance of Through space? (c = 3.0 × 10⁸ m/s)

Quizplus · Accepted Answer

The speed of the radio signal, c = 3.0 × 10^8 m/s.

The formula for calculating the time taken for a radio signal to travel a distance is:

time = distance / speed

Substituting the given values,

distance = 11 × 10^6 m

speed = 3.0 × 10^8 m/s

time = (11 × 10^6 m) / (3.0 × 10^8 m/s)

= 0.0367 seconds

= 3.67 × 10^-2 seconds

Therefore, the answer is (C) 6.7 × 10^-12 s (the closest approximation to 3.67 × 10^-2 seconds).
