## Practice MCAT Question - Q8 - Answer!

**Light is incident on a prism at an angle of 90° relative to its surface. The index of refraction of the prism material is 1.50. Which of the following statements is most accurate?**

**A.**The angle of refraction will be greater than 0° but less than 45°.

**B.**The angle of refraction will be greater than 45° but less than 90°.

**C.**The angle of refraction will be 0°.

**D.**The angle of refraction cannot be determined from the information given.

*The correct answer is (C). Snell’s law is n*

_{1}sin(theta_{1}) = n_{2}sin(theta_{2}). Since the incident rays are normal to the prism surface, theta_{1}= 0°, and sin 0° = 0. Since*0 = n*

_{2}sin(theta_{2})*theta*

_{2}= 0**Check The Sidebar For Another**
