A Doppler weather radar operates at a frequency of 3.40 GHz. The wave from this radar system reflects from an approaching weather system moving with a speed of 39.0 m/s. What is the difference in frequency between the outgoing and returning waves?

Question

Quizplus · Accepted Answer

The Doppler shift formula for frequency is given by Δf = (2 * v * f) / c, where v is the speed of the object, f is the original frequency, and c is the speed of light. Substituting the given values: Δf = (2 * 39.0 m/s * 3.40 GHz) / (3.00 x 10^8 m/s) = 442 Hz.
