What is the frequency in megahertz of a radio set that is broadcasting at 99.9 meters?

(1 Hz = 1 cycle per second; speed of light = [tex]3.0 \times 10^8 \, \text{m/s}[/tex]; 1 nm = [tex]1.0 \times 10^{-9} \, \text{m}[/tex])

A. 3.00 MHz
B. 15.7 MHz
C. 33.3 MHz
D. 299 MHz

Answer :

The frequency in megahertz of a radio set that is broadcasting at 99.9 meters is 3.00 Mega hertz.

So option A is correct.

What is frequency?

Frequency is referred to as the number of occurrences of a repeating event per unit of time which is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency.

Frequency and wavelength are important characteristics of a wave cycle. We know that wavelength refers to the distance between any two corresponding points on adjacent waves while frequency is the number of waves that pass, in a specified amount of time, at a certain point.

From the question above

wavelength = 9.99 m

velocity = 3.0 * 10^ 8

Frequency =?

Frequency = velocity/ wavelength

frequency = 3.0 * 10^ 8 / 9.99 m

frequency = 3003003.003

frequency= 3.0 Megahertz.
