  • A charged particle oscillates about its mean equilibrium position with a frequency of 109 Hz. The electromagnetic waves produced: a) fall in the region of radio waves b) will have a wavelength of 0.3 m

A charged particle oscillates about its mean equilibrium position with a frequency of 109 Hz. The electromagnetic waves produced:

a)   fall in the region of radio waves

b)    will have a wavelength of 0.3 m

c)    will have a frequency of 109 Hz

d)    will have a frequency of 2 × 109 Hz

Answers (1)

Answer: The correct answers are the options,

a.    fall in the region of radio waves
b.    will have a wavelength of 0.3 m
C.    will have a frequency of 109 Hz

Here, the particle that produces electromagnetic waves of frequency is equal to the frequency at which it oscillates about its mean equilibrium position.

So, the frequency of electromagnetic waves produced by the charged particle is v= 109 Hz.

Wavelength (\lambda ) = c/v = 3 \times 108 /109 = 0.3 m

The 109 Hz frequency falls under the radio wave region.
