What is meant by the wavelength of light? By its frequency? Show how they are related to each other
What will be an ideal response?
The wavelength is the distance between successive wave crests, while the frequency is the number of waves that pass the observer per second. All forms of EM radiation travel in a vacuum at 300,000 km/sec., and this velocity is the product of the wavelength X the frequency of the radiation.
