The speed of electromagnetic waves in a vacuum is 3.0 × 108 m/s.
The wavelength of a beam of green light is 5.0 × 10-7 m.
Calculate the frequency of this green light.
State the unit.
Use the equation:
frequency=speedwavelength \text{frequency} = \frac{\text{speed}}{\text{wavelength}} frequency=wavelengthspeed
