Electromagnetic waves travel at a speed of 3.0 x 108 m/s. A radio station transmits waves with a wavelength of 2.5 x 102 m.
Calculate the frequency of the radio waves.​

1.2×10⁶ Hz

Explanation:

Applying,

v = λf Equation 1

Where v = speed of wave, λ = wavelength, f = frequency.

make f the subject of the equation

f = v/λ Equation 2

From the question,

Given: v = 3.0×10⁸ m/s, λ = 2.5×10² m

Substitute these values into equation 2

f =  3.0×10⁸/2.5×10²

f = 1.2×10⁶ Hz

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
