LAW OF REFRACTION

• Refraction is the bending of light as it enters a different optical medium.
• This bending of light is associated with the absolute index of refraction of the medium
• formula of index of refraction

  n=c/v
• Speed of light in vacuum - fastest speed of light
• As a ray of light passes obliquely through the boundary between two materials with different indices of refraction, the ray bends
• If medium 1 is higher than medium 2 , then angle of reflection is greater
• If medium 2 is higher than medium 1, then angle of incident is greater
