Question

AB is light ray travelling from liquid to air BC and BD are refracted rays

Answer 1

Answer:

The refracted rays BC and BD move away from the normal .

Explanation:

In the above case:

       Denser medium : liquid

       Rarer medium : air          

If a light ray passes from  a denser to rarer medium, the refracted ray moves away from the normal.

If a light ray passes from  a rarer to denser medium, the refracted ray moves towards the normal.

Answer 2

(i) BD is the refracted ray if the liquid taken is benzene

(ii) BC is the refracted ray if the liquid taken is water

Explanation:

The complete question is:

Observe the following figure AB is light ray travelling from liquid to air BC and BD are refracted rays. Which is the refracted ray if

(i) the liquid taken is benzene?

(ii) the liquid taken is water?

( The absolute refractive index of water and benzene are 1.3 and 1 .5)

The figure is attached

Solution:

Given that the refractive index of water and benzene are 1.33 and 1.5 respectively

Therefore, it is clear that water is a rarer medium than benzene

We know that

When a ray of light travels from rarer to denser medium it deflects towards the normal, the denser the medium, the greater is the deflection towards the normal

from the given attached figure it is clear that the ray BD is deflected more towards the normal than that of ray BC

Therefore, BD is the refracted ray if the liquid taken is benzene

And, BC is the refracted ray if the liquid is taken as water

Hope this answer is helpful.
