Question

A radio station transmits waves of wave length 200m.If the speed of the waves is 3×10^8 m/s, find the frequency of the radio station. ​

Answer 1

Answer:

The frequency of Radio Station is 1.5×10⁶Hz

Explanation:

Given, Wavelength of the waves=200m

Speed of waves=3×10⁸m/s

To find, the frequency of Radio station.

We know that

speed=wavelength×frequency

from the above equation we can write the equation for frequency as follows

frequency=$\frac{speed}{wavelength}$

Substituting the values in above equation

frequency=$\frac{3}{200}$×10⁸s⁻¹

⇒frequency=0.015×10⁸s⁻¹

⇒frequency=1.5×10⁶s⁻¹ or 1.5MHz
