see the above tagged pic and tell the answer​

Answer 1

Answer:

a)refractive index have no si units, since from the definition refractive index is the ratio of velocity of light in a material divided with velocity of light in vacuum

b)Glass is denser than water. Whereas, Density of Water=9.97*10^3 kg/m^3. Theoretically, Water is a liquid and hence have high intermolecular space whereas glass is a amorphous solid having irregular but comparatively lower intermolecular space.

or

speed of light in glass is less than that of water.

c)The velocity of light in glass medium is `2 xx 10^(8)m//s

d)diamond
