What is Light?
Light is a form of energy, called Electromagnetic Radiation. Light travels very fast (around 300,000 km/s) and goes straight. Light rays travel only straight lines, but they can be bend by a proper material.
Why does light have so many different colours?
There are different colours of light because they are light waves which have different wavelengths. Red light has the longest wavelength while violet light has the shortest wavelength
Blocking- blocking a light will create a shadow
Reflecting - reflecting light with a mirror to change its way.
Bending- also called refraction- going from one medium to another.
