A convex lens is made of a material of refractive index n2 is kept in a medium of refractive index n1.A parallel beam of light is incident on the lens. Complete the path of light emerging from the convex lens if 1) n1 < n2 2)n1=n2 3)n1>n2 Please provide the reasons as well

Expert Answer:

you can understand this from the concept that the light rays bend away from normal as they enter from denser to rarer medium. that causes the light rays to diverge in the second case.
