What is the wavelength of an electromagnetic wave that travels at 3 x 108 m/s and has a frequency of 60 MHz? (1 MHz = 1,000,000 Hz)

Respuesta :

Wavelenght is the distance between two crests of a wave. The formula for that is

λ = v/f

where λ is the wavelenght, v is the speed and f is the frequency. To slove this, we first convert the frequency to basic units:

60 MHz = 60,000,000 Hz

Then we put the frequency and the speed at the formula:

λ = 3*108/60000000

λ = 0.0000054 m


The wavelength of an electromagnetic wave that travels at 3 x 108 m/s and has a frequency of 60 MHz is 5m

The formula for calculating the wavelength of the electromagnetic wave is expressed as:

λ =v/f where

  • v is the velocity
  • f is the frequency

Given the following parameters

f = 60MHz = 60,000,000Hz

v = 3 x 10⁸ m/s

Substitute the given parameters into the formula as shown:

[tex]\lambda =\frac{3 \times 10^8}{6 \times 10^7} \\\lambda = \frac{3}{6} \times 10^{8-7}\\\lambda = \frac{1}{2} \times 10\\\lambda = 5m[/tex]

Hence the wavelength of an electromagnetic wave that travels at 3 x 108 m/s and has a frequency of 60 MHz is 5m.
