1. Human being perceive objects because of light. Light source are of two types- primary and secondary.
2. The sun and Lamps are example of primary light sources.

Nature of Light 

wavelength- wavelength is the distance between two successive wave crests or wave troughs in the direction of travel.

Amplitude- Amplitude is the maximum distance the oscillation travels, away from its horizontal axis.

Frequency- The frequency of vibration is the number of waves crossing at a point.
