write 3 differences between reflection and refraction
Reflection:
When light falls on a surface, the direction of the ray is changed. This change in direction is known as reflection of light. The reflected light travels to the same medium it came from.
Refraction:
The phenomenon of bending of light from its straight line path as it passes obliquely from one transparent medium to another is called refraction of light. It occurs because the speed of light is different in different media.
