Question 10

Microwaves are electromagnetic waves used to transmit telemetry data from a lunar landing module back to a ground station on Earth. A microwave signal transmitted from the lunar surface takes 1.28 s1.28\text{ s}1.28 s to reach the Earth station.

The speed of electromagnetic waves is 3.0×108 m/s3.0 \times 10^8\text{ m/s}3.0×108 m/s.

Calculate the distance between the Earth station and the lunar landing module. Use the equation:

distance=speed×time \text{distance} = \text{speed} \times \text{time} distance=speed×time
