Question

Calculate the wavelength of a radio wave with a frequency of 93.1 x 10^6 ^-1

Answer 1

Wave speed = frequency x wavelength

therefore wavelength = wave speed / frequency

the speed of radio waves ( and all electromagnetic waves in vacuum) is 3 x 10^8 meters per second

just put the numbers in now ☺

Answer 2

Answer:  3.22 m

Explanation:

The relationship between wavelength and frequency of the wave follows the equation:

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

where,

$\nu$ = frequency of the wave =$93.1\times 10^6s^{-1}$

c = speed of light =$3\times 10^8ms^{-1}$

$\lambda$ = wavelength of the wave

Now put all the given values in this formula, we get

$\lambda=\frac{3\times 10^8ms^{-1}}{93.1\times 10^6s^{-1}}$

$\lambda=3.22m$

Thus wavelength of a radio wave with a frequency of $93.1\times 10^6s^{-1}$ is 3.22 m.
