Question

25 POINTS. Radar used microwaved yo check the speed of cars. If a speed of the microwaves is 2 000 000 m/ s and the wavelength is 0.0345m calculate the frequency.

Answer 1

57971014.49 Hz or 5.79 * 10^7 Hz

Explanation:

Given that:

Speed of microwave (v) = 2,000,000 m/s

Wavelength, λ = 0.0345 m

Frequency :?

Using the relation :

v = fλ

f = v / λ

f = 2,000,000 / 0.0345

f = 57971014.49 Hz
