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°
