Question

A concave lens made up of a material of refractive index and one is kept in a medium of refractive index and to a parallel beam of light is incident on the lens trace the path of the ray of light parallel to the principal axis incident on the country flags after refraction first n is greater than n2

Answer 1

Yes, that's right.If a concave lens made up of a material of refractive index and one is kept in a medium of refractive index and to a parallel beam of light is incident on the lens trace the path of the ray of light parallel to the principal axis incident on the country flags after refraction first n is greater than n2.

If it helps then please mark as brainliest.

Answer 2

Yes it's right.
(a) In this case, n1 > n2, i.e. medium of concave lens is denser than the medium from where light ray 
is incident on it. Therefore, at entering surface, the light ray bends towards the normal N1, while leaving the  lens, the ray again goes under refraction at leaving surface and in this situation it bends away from the normal N2

Hope it helps you.
