\(n1sen\theta^{1=}n2\ sen\theta^2\)
\(1.0003\left(sen\theta^1\right)=1.33\left(sen\ 33\right)\)
\(\theta^{-1}\left[\frac{1.333}{1.0003}sen\ 33\right]46.90\)
\(\theta^{3\ }90-46.90=43.60\)
Exercise 7
A ray of light in the air collides with a glass slab and the n = 1.56 is partially reflected and refracted. Determine the angle of incidence if the angle of reflection is twice the angle of refraction
