It occurs when light bounces off a surface or object, changing direction
It is a phenomenon that takes place due to the bending of light when it travels from medium to another.

Refraction
Why is red color least bent as light passes through a prism?
This is because wave with longer wavelengths are heavier waves. More energy is required to move them in a different direction and red light has the longest wavelength.
Because it has the shortest wavelength.
Because it has the highest energy.
When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red)the process is called Reflection.
True
False
Rainbow is a phenomenon we usually seen in the sky after the rain. Why?
It occurs due to dispersion of sunlight by tiny water droplets, present in the atmosphere. A rainbow is always formed in a direction opposite to that of the Sun to facilitate easy dispersion on sunlight.
The rain drops are reflecting the light back to the source.
