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

Step-by-step explanation:

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

`\\u=(c)/(\lambda)`

where,

`\\u` = frequency of the wave =
`93.1* 10^6s^(-1)`

c = speed of light =
`3* 10^8ms^(-1)`

`\lambda` = wavelength of the wave

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

`\lambda=(3* 10^8ms^(-1))/(93.1* 10^6s^(-1))`

`\lambda=3.22m`

Thus wavelength of a radio wave with a frequency of
`93.1* 10^6s^(-1)` is 3.22 m.
