Question

Find the refractive index of a material if angle
of incidence of ray of light is 45 and angle of
refraction in material is 30°

Answer 1

R.I=sine of angle of incidence/sine of angle of refraction

R.I=sin45/sin30

R.I=

SIN45

$\frac{1}{\sqrt{2} }$

sin 30

1/2

R.I=1.414

$\sqrt{2} = 1.414$
