Question

Refraction of light through a prism

Answer 1

Answer

• Refraction is the bending of light when it goes from one medium to another so, when a ray of light passes through a glass prism, refraction of light occurs both, when it enters the prism as well as when it leaves the prism. ... In this case the ray of light is deviated on passing through the prism.
• When a light ray falls normally on a polished surface (like a mirror), it will reflect along the same path. If the surface is transparent (example: glass slab or Prism), the ray will pass through it without any deviation.
