Question

What is the wavelength of the carrier wave of a campus radio station, broadcasting at a frequency of 97.2 MHz (million cycles per second or million hertz)?

Answer 1

Answer:

Wavelength is 3.08 meters.

Explanation:

It is given that,

Frequency, $f=97.2\ MHz=97.2\times 10^6\ Hz$

We need to find the wavelength of the carrier wave of a campus radio station. It can be calculated by using following relation as :

$c=f\times \lambda$

$\lambda=\dfrac{c}{f}$

$\lambda=\dfrac{3\times 10^8\ m/s}{97.2\times 10^6\ Hz}$

$\lambda=3.08\ m$

So, the wavelength of the carrier wave is 3.08 meters. Hence, this is the required solution.
