Question

(a)
Water has refractive index 1.33 and alcohol has refractive index 1.36.
Which of the two medium is optically denser ? Give reason for your
answer.
b) Draw a ray diagram to show the path of a ray of light passing
obliquely from water to alcohol.
) State the relationship between angle of incidence and angle of
refraction in the above case.​

Answer 1

Answer:

a) Alcohol is optically denser than water. This is because greater the refractive index more dense the liquid
