Light moves from flint glass (n = 1.66) into
water at an angle of incidence of 26.0°.
a) What is the angle of refraction?

Explanation:

Through Snell's Law, we can solve this.

The formula is:

[tex]n1 \times \sin(theta1) = n2 \times \sin(theta2) [/tex]

n1 = flint = 1.66

n2 = water = 1.33

theta1 = 26.0°

theta2 = angle of refraction

Substituting these values in the formula,

[tex]1.66 \sin(26) = 1.33 \sin(x) \\ \frac{1.66 \sin(26) }{1.33} = \sin( x ) \\ 0.5471 = \sin(x) \\ arcsin(0.5471) = x \\ 33.17 = x[/tex]

Therefore, the angle of refraction is 33.17°
