Question

Radio waves travel at 3.00 · 108 m/s. Calculate the wavelength of a radio wave of frequency 600 kHz. (6.00 · 105 Hz).

1.80 x 1014

5.56 x 10-15

2.00 x 10-3

5.00 x 102

Answer 1

Hmm, I got that the wavelength is 500 meters.

Answer 2

Wavelength of the radio wave is 500 m.

Step-by-step explanation:

It is given that,

Speed of radio waves,
`v=3* 10^8\ m/s`

Frequency of the wave,
`f=600\ kHz=600* 10^3\ Hz=6* 10^5\ Hz`

We have to find the wavelength of the radio waves. The wavelength of a wave is given by :

`\lambda=(v)/(f)`

`\lambda=(3* 10^8\ m/s)/(6* 10^5\ Hz)`

`\lambda=500\ m`

or

`\lambda=5* 10^2\ m`

So, the correct option is (d). Hence, this is the required solution.
