Radio Waves Formula and Examples

Radio Waves Formula :

The formula to calculate the radio waves is given by,

vr = λv

where,

vr→ speed,

λ→ wavelength, and

v →frequency of the radio wave.

Sample Problems :

Example 1 :

Calculate the speed of a radio wave having a wavelength of 290 m and a frequency of 2 MHz.

Solution :

We have,

λ = 290

v = 2 × 106

Using the formula we have,

vr = λv

= 290 (2*106)

= 5.8 × 107 m/s.

Example 2 :

Calculate the speed of a radio wave having a wavelength of 36 m and a frequency of 3 MHz.

Solution :

We have,

λ = 36

v = 3 × 106

Using the formula we have,

vr = λv

= 36 (3 × 106)

= 10 × 107 m/s.
