Question

If the ray incidents with an angle of 45 on a prism gets refraction with an angle of 30 then refractive index of prism

Answer 1

n=sin I/sin r=sin 45/sin 30=(1/√2)/(1/2)=2/√2=√2

Answer 2

Answer:$\sqrt{2}$

Explanation:

n=$\frac{sin i}{sin r}$=$\frac{\frac{1}{\sqrt{2} } }{\frac{1}{2} }$=$\sqrt{2}$
