The Velocity Of Radiowaves Is 3x10 Kms The Frequency Corresponding Physics Question

The velocity of radio-waves is 3×10⁵ km/s. The frequency corresponding to wavelength of 300 m is

Options

(a) 1 MHz
(b) 10 MHz
(c) 1 kHz
(d) 10 kHz

Correct Answer:

1 MHz

Explanation:

Frequency ʋ = Velocity v / Wavelength λ = v / λ

⇒ ʋ = (3 × 10⁵ × 10³) / 300 = 10⁶ Hz = 1 MHz
