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

Carry energy
-
Speed (s)
-
Frequency (v) - The number of waves or cycles per unit of time,
generally reported in units of cycles per second or hertz (Hz).
-
Wavelength
(
)
- 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.

Low Frequency
The product of the frequency and the wavelength is equal to the speed of
a wave.
-
For electromagnetic radiation, the speed of the waves is equal to the speed
of light.

Visible light lies between the range 700 nm (red) to 400 nm
(violet).
