Question

Radio stations use electromagnetic waves for broadcasting. The chart shows different frequencies of waves used by radio stations. Which radio station has the wave with the longest wavelength?

Answer 1

Radio Station W as the slower the frequency the longer the wave length

Answer 2

Answer: radio station W

Step-by-step explanation:

The wavelength of a radio wave is given by:

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

where

c is the speed of light

f is the frequency of the wave

From the equation, we see that the wavelength is inversely proportional to the frequency: the higher the frequency, the shorter the wavelength, the lower the frequency, the longer the wavelength.

Therefore, the waves with longest wavelength are the waves with lower frequency: therefore, the waves emitted by radio station W.
