Calculate the wavelength of each frequency of electromagnetic radiation: 1050 khz (typical frequency for am radio broadcasting) (assume four significant figures)

The wavelength of given electromagnetic radiation is 285.7 m

Explanation:

To calculate the wavelength of the electromagnetic radiation, we use the equation:

where,

= frequency of the electromagnetic radiation =      (Conversion factor:  1 kHz = 1000 Hz)

= wavelength of the electromagnetic radiation = ?

c = Speed of light =

Putting values in above equation, we get:

Hence, the wavelength of given electromagnetic radiation is 285.7 m

it would be kevlar ^^
