A ray of light travels from a glass-to-liquid interface at an angle of 23°.Indices of refraction for the glass and liquid are,respectively,1.58 and 1.80.What is the angle of refraction for the ray moving through the liquid?
A)26.4°
B)20.1°
C)17.5°
D)20.2°
E)26.2°

Using Snell's Law, n1 * sin(theta1) = n2 * sin(theta2), where n1 = 1.58, theta1 = 23°, n2 = 1.80. Solving for theta2 gives approximately 20.1°.
