Question 45

Light travels from water into air.

What is the relationship between the refractive index n n\,n of the water, the angle of incidence i i\,i in the water, and the angle of refraction r r\,r in the air?

A

n=sin⁡isin⁡rn = \frac{\sin i}{\sin r}n=sinrsini​

B

n=sin⁡rsin⁡in = \frac{\sin r}{\sin i}n=sinisinr​

C

n=irn = \frac{i}{r}n=ri​

D

n=rin = \frac{r}{i}n=ir​
