Question

A radio station broadcasts at 620 khz . if the radio waves travel at a velocity of 3× 10⁸ m/s² . calculate the wavelength of the radio waves​

Answer 1

Answer:

Wavelength of the radio wave is 483.87 m

Explanation:

Frequency of radio wave is $f=620 kHz$

Velocity of radio wave is $c=3\times 10^8 m/s$

Wavelength is given by

$\lambda =\frac{c}{f} \\\\\lambda =\frac{3\times 10^8}{620 \times 10^3} \\\\\lambda =483.87 m$

Wavelength of the radio wave is 483.87 m

Answer 2

Answer:

483.87m

Wavelength of the radio wave is 483.87 m

Explanation:

Frequency of radio wave is f 620kHz

Velocity of radio wave is c = 3 x 108m/s

Wavelength is given by

3 x 108

λ = 620 × 103

λ = 483.87m

Wavelength of the radio wave is 483.87 m
