Answer:
The wavelength of radio waves is 2.85 m.
(B) is correct option.
Explanation:
Given that,
Frequency = 105 MHz
We need to calculate the wavelength of radio waves
Using formula of wave velocity
Where, v = wave speed
f = frequency
= wavelength
Put the value into the formula
Hence, The wavelength of radio waves is 2.85 m.
