What is the wavelength of an electromagnetic wave that travels at 3 10 m/s and has a frequency of 60 mhz? (1 mhz = 1,000,000 hz)?

Explanation:

As we know the electromagnetic waves can travel through the vacuum with speed

now we also know that the frequency of the electromagnetic waves is given as

so the wavelength of the electromagnetic waves is given as

so it is given as

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
