what is relation between the focal length of lense and it's Refractive index

Answers

Answered by habibqureshii

Answer:The focal points will not lie a focal length away, but the focal length multiplied by the refractive index. This means that if there is different medii on the two sides, the two focal points will have a different distance to the lens (actually to the principal planes).
