Question

Refractive Index of water and glass are 4/3 and2/3 respectively. A ray of light travelling in water
incident

Answer 1

hey buddy here is your answer

Refractive index of medium 1 w.r.t. medium 2 is given by,

2  μ  1=μ1/μ2

Hence according to question,

Refractive index of glass,μg=3/2

Refractive index of water, μw =4/3

​

Hence w μ g=9/8=1.125
