Detailed Solution

A radio station transmits a

219 m

wavelength and

1370 kHz

frequency. Then the velocity of the wave transmitted is

3 \times 10

m / s .

Given the wavelength of the wave,

λ = 219 m

Frequency of wave

v = 1370 kHz

\Rightarrow

= 1370 \times 10

Hz

We know that

The velocity of the wave, V = Frequency (v) \times wavelength (λ)

\Rightarrow V = vλ

\Rightarrow V = 1370 \times 10

Hz \times 219 m

\Rightarrow V = 3 \times 10

m / s

.
Hence the velocity of radio wave

V = 3 \times 10

m / s
