Answer: R = 28 degree
Explanation:
The given parameters are:
Refractive index n = 1.52
Incident angle I = 45 degree
According to Snell law,
Sin I/Sin R = n
Where
I = angle of incidence
R = angle of refraction
n = refractive index
Substitute all the parameters into the formula
1.52 = sin 45/ sin R
Make sinR the subject of formula
Sin R = sin 45/1.52
Sin R = 0.46520
R = sin^-1(0.46520)
R = 27.72 degree
Therefore, the angle of refraction will be 28 degrees approximately.
