Question

If we want to produce electromagnetic waves of wavelength 500 km by an oscillating charge then frequency of oscillating charge must be

Answer 1

Answer:

Frequency of the electromagnetic waves is 600 Hz

Explanation:

As we know that frequency of electromagnetic waves is the ratio of speed of waves and its wavelength

So we will have

$f = \frac{c}{\lambda}$

here we know

$c = 3 \times 10^8 m/s$

$\lambda = 500 km$

$\lambda = 5 \times 10^5 m$

so we have

$f = \frac{3 \times 10^8}{5 \times 10^5}$

$f = 600 Hz$
