Question

We love blasting our radio in the morning to wake up. Radio waves are used to transmit information on various channels. Calculate the wavelength of a radio wave that has a frequency of 5.4 x 10^10 Hz

Answer 1

wavelength = 0.56 × 10⁻² m

Step-by-step explanation:

Given data:

Frequency of radiation = 5.4 × 10¹⁰ Hz

Wavelength = ?

Solution:

Formula:

speed of light = wavelength × frequency

wavelength = speed of light / frequency

wavelength = 3 × 10⁸ m/s / 5.4 × 10¹⁰ Hz ( Hz= 1/s)

wavelength = 0.56 × 10⁻² m
