Snell's Law Practice

A ray of light traveling from air into crown glass strikes the surface at an angle of 30 degrees. What is the angle of refraction? (air n=1, crown glass n=1.532)

• 39.7 degrees
• 19.2 degrees
• 59.1 degrees
• 12.3 degrees

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.

Glass has a _____________ index of refraction than air.

• Equal
• Greater
• Less
• Impossible to say
