    The speed of light depends
    (a) on elasticity of the medium only
    (b) on inertia of the medium only
    (c) on elasticity as well as inertia
    (d) neither on elasticity nor on inertia
    digAnsr:   d
    Ans : (d) neither on elasticity nor on inertia
    The speed of light in any medium depends on the refractive index of that medium, which is an intensive property. Hence, speed of light is not affected by the elasticity and inertia of the medium.
