Question

A particular station of All India Radio, New Delhi, broadcasts on a frequency of 1,368 kHz (kilohertz). The wavelength of the electromagnetic radiation emitted by the transmitter is: [speed of light, .c=3.0 × 108 ms -1] (A) 219.3 m (B) 219.2 m (C) 2192 m (D) 21.92 cm

Tardigrade Admin · Accepted Answer

Wavelength (λ)=(c/v) c is speed of light v is frequency λ=(3 × 108/1368 × 103)=219.298 m =219.3 m

Q. A particular station of All India Radio, New Delhi, broadcasts on a frequency of $1, 368 k Hz$ (kilohertz). The wavelength of the electromagnetic radiation emitted by the transmitter is : [speed of light, $c = 3.0 \times 1 0^{8} m s^{- 1}]$

219.3 m

219.2 m

2192 m

21.92 cm

Wavelength $(λ) = \frac{c}{v}$
$c$ is speed of light
$v$ is frequency
$λ = \frac{3 \times 1 0 ^{8}}{1368 \times 1 0 ^{3}} = 219.298 m = 219.3 m$
