The speed of electromagnetic waves in a vacuum is 3.0 × 108 m/s.
The wavelength of a beam of red laser light is 6.0 × 10-7 m.
Calculate the frequency of this red light.
State the unit.
Use the equation:
frequency=speedwavelength \text{frequency} = \frac{\text{speed}}{\text{wavelength}} frequency=wavelengthspeed64 exam-style questions on Edexcel GCSE Physics 4.1 Wave properties, covering 4.1.1 Waves transfer energy and information, 4.1.2 Frequency, wavelength, amplitude, period and wavefronts, 4.1.3 Longitudinal and transverse waves, 4.1.4 The wave speed equations, 4.1.5 Measuring wave velocity, and 4.1.6 Calculating depth or distance from waves.
