Question

Find the frequency
of an electromagnetic wave in a vacuum with a
wavelength of 0.02 m.​

Answer 1

Answer: Frequency = 1.5 × 10¹⁰ Hz.

Explanation:

wavelength = 0.02 m

c = speed of light = 3 × 10⁸ m/s

c = wavelength × frequency

Frequency = c ÷ wavelength

Frequency = 3× 10⁸ ÷ 0.02

Frequency = 1.5 × 10¹⁰ Hz.
