Structure : Electromagnetic Radiation
Electromagnetic Radiation - Radiation that contains
both electric and magnetic components and travels at the speed of light (2.998
x 108 m/s).
Wave-like properties of electromagnetic radiation
Frequency (v) - The number of waves or cycles per unit of time,
generally reported in units of cycles per second or hertz (Hz).
- The smallest distance between repeating points on a wave.
Amplitude - The distance between the highest (or lowest) point on a wave
and the center of gravity of the wave.
The product of the frequency and the wavelength is equal to the speed of
For electromagnetic radiation, the speed of the waves is equal to the speed
Visible light lies between the range 700 nm (red) to 400 nm
