What is light wave?

• It is an electromagnetic wave where vibration of particles is perpendicular to the direction of propagation of wave.
• It requires no medium to travel.
• Light wave consists of different wavelength regions.

• Electromagnetic spectrum of light has Ultra-Violet region, Visible region and infrared region.

• Speed of light is 3 X 10^8 m/s in vacuum which is 3 X 10^10 cm/sec.
