Microwaves are electromagnetic waves used to transmit signals from Global Positioning System (GPS) satellites to Earth. A microwave signal transmitted from a GPS satellite takes 0.068 s0.068\text{ s}0.068 s to reach a receiver on the Earth's surface. The speed of microwaves is 300 000 000 m/s300\,000\,000\text{ m/s}300000000 m/s.
Calculate the distance between the GPS satellite and the receiver.
Use the equation:
distance=speed×time \text{distance} = \text{speed} \times \text{time} distance=speed×time29 exam-style questions on AQA GCSE Physics 6.2 Electromagnetic waves, covering 6.2.1 Types of electromagnetic waves, 6.2.2 Properties of electromagnetic waves 1, 6.2.3 Properties of electromagnetic waves 2, 6.2.4 Uses and applications of electromagnetic waves, 6.2.5 Lenses, and 6.2.6 Visible light.
