32. Observe the following figure. AB is light ray travelling from liquid to
air. BC and BD are refracted rays.
i) Which is the refracted ray if the liquid taken is benzene?
ii) Which is the refracted ray if the liquid taken is water?
Justify your answer. (The absolute refractive index of water and benzene
are 1.33 and 1.5 respectively)
Answers
Answer:
here D ray is benzene and C is water
Explanation:
we know that benzene is more denser than water..
when ray travels from rarer to denser medium it bends towards the normal.
in this case benzene ray bends more , towards the normal being more denser.
hence it moves less away from normal when it moves from denser to rearer.
(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:
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.
