Determine the frequency of a microwave 6 cm in length. (A microwave is an electromagnetic wave. It travels through space at a speed of 3.0 x 10^8 m/s)

Answer:

Wavelength of microwave (λ) = 6 cm = 6 x 10^-3 m
Speed of wave © = 3 x 10^8 m/s

Let the frequency of the wave be denoted by the symbol, ν.

The required equation is,
c=λ×ν
3 x 10^8 = (6 x 10^-3) x ν
So, frequency of wave = ν = 5 x 10^10 Hz
