Question

Frequency of an E.M. waves is 10 MHz then its wavelength is :

Answer 1

Explanation:

from the formula

λ= v/f

where

λ

is the wavelength

f

is the frequency and

v

is the speed

v = 299792458 m/s

because it is electromagnetic wave

f = 10^7 Hz

$wavelenght = v \div f \\ = 299792458 \div {10}^{7 } = 29.9792458$

marks as brainliest...
