Question

Secondary SchoolPhysics 5 points A ray of light incident on a rectangular plate at an angle 60° the light ray suffers a deviation which is 25% of the angle of incidence the refractive index of the glass will be

Answer 1

Sin i/sin r=sin 60/sin 45=root3/2*root 2=root (3/2)

Answer 2

Explanation:

i=60

r=25/100×60

r=15

mew=sin60/sin15

mew=√3/2/√3-1/2√2

mew=
