The speed of electromagnetic waves in dry air is 3.0 × 108 m/s.
The wavelength of a microwave signal transmitted between two telecommunication towers is 1.2 × 10-2 m.
Calculate the frequency of this microwave signal.
State the unit.
Use the equation:
frequency=speedwavelength \text{frequency} = \frac{\text{speed}}{\text{wavelength}} frequency=wavelengthspeed
