Question

Announcers at a certain radio station say that they are at "95 FM on your dial," meaning that they transmit at a frequency of 95 MHz (95 megahertz, or 95 million cycles per second). What is the wavelength of the radio waves from this station

Answer 1

Answer:

$\lambda=3.15\ m$

Explanation:

Frequency of the FM, $f=95\ MHz=95\times 10^6\ Hz$

We need to find the wavelength of the radio waves from this station. The relationship between the frequency and the wavelength is given by :

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

c is the speed of light

$\lambda=\dfrac{3\times 10^8\ m/s}{95\times 10^6\ Hz}$

$\lambda=3.15\ m$

So, the wavelength of the radio waves from this station is 3.15 meters. Hence, this is the required solution.
