Concept introduction:
Light is measured by its wavelength (in nanometres) or frequency (in Hertz).
One wavelength equals the distance between two successive wave crests or troughs.
Frequency (Hertz) equals the number of waves that passes a given point per second.
The relation between the
Here,
The frequency of the electromagnetic radiation is used to determine the amount of energy, which is carried by one of its photons.
The energy of the photon is directly proportional to the frequency.
Here,
The relation between a nanometer and a meter is as:
The conversion factor to obtain the units of wavelength in
