If the refractive index of M1 is higher than that of M2, then a ray of light going from M2 to M1 will
Bend towards the normal

If the refractive index of medium A is higher than that of the medium B, then a ray of light going from B to A will
The plane mirrors M1 and M2 are inclined to each other such that a ray of light incident on mirror M1 and parallel to the mirror M2 is reflected from mirror M2 parallel to the mirror M1. The angle between the two mirror is (in degrees)
Two spheres of masses m1 and m2 (m1>m2) respectively are tied to the ends of a light, inextensible string which passes over a light frictionless pulley. When the masses are released from their initial state of rest, the acceleration of their centre of mass is:
