- Homework Statement
- The following expression sin ϑ = 1 / n applies to the angle of total reflection at the transition of the beam from glass to air. For how much

changes the angle if the refractive index changes by 10^−6?

For n take 1.5. Express the result only with n.

- Relevant Equations
- sin(ϑ) = 1/n(water)

Solution:

(delta (ϑ)) =

-(minus delta n) /(n*sqrt((n^2-1)))

(delta (ϑ)) =

-(minus delta n) /(n*sqrt((n^2-1)))
