The frequency of the radio wave is 1 × 10⁸ Hz
What is Frequency ?
Frequency is the number of occurrences of a repeating event per unit of time.
It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency.
Formula to use :
C = λ × v
- C represents the speed of light, which has a value of approximately 3.00 × 10⁸ m/s
- λ represents the wavelength and the units should be in meters.
- v represents the frequency, which should have units of Hz or s⁻¹.
Hz is hertz or reciprocal seconds.
Now let's rearrange the equation to solve for v :
C λ = v
v = 3.00 × 10⁸ m/s / (3m)
= 1 × 10⁸ s⁻¹.
Therefore, The frequency of the radio wave is 1 × 10⁸ Hz.
