Question

46. The refractive index of flint glass is 1.65 and that for alcohol is 1.36 with respect to air. what is the refractive index of the flint goes with respect to alcohal? A .o. 82 B. 1.21 C.1.11 D .1.01​

Answer 1

Answer:

ans B

refractive index for flint glass with respect to air μ1=1.65

refractive index for alcohol with respect to air μ2=1.36

now refractive index of glass with respect to alcohol μ3.

⇒ μ3=μ1μ2

⇒ μ3=1.651.36

∴μ3=1.21

Thus, the refractive index of dense flint glass with respect to alcohol μ3 is equal to 1.21.

Explanation:

refractive index for flint glass with respect to air μ1=1.65

refractive index for alcohol with respect to air μ2=1.36

now refractive index of glass with respect to alcohol μ3.

⇒ μ3=μ1μ2

⇒ μ3=1.651.36

∴μ3=1.21

Thus, the refractive index of dense flint glass with respect to alcohol μ3 is equal to 1.21.
