NEET 2021 · ChemistryPrevious Year Question

A particular station of All India Radio, New Delhi, broadcasts on a frequency of $1368$ kHz (kilohertz). The wavelength of the electromagnetic radiation emitted by the transmitter is: [Speed of light, $c = 3 \times 1 0^{8}$ m s $^{- 1}$ ]

Answer: (C) 219.3 m. \textbf{Answer:} (C) 219.3 m \textbf{Solution:} $λ = \frac{c}{ν} = \frac{3 \times 1 0 ^{8}}{1368 \times 1 0 ^{3}} = 219.3$ m.
