A light ray contacts a surface of a different medium that can transmit light. What happens to the incident light?

• It can reflect some of the incident light

• It can refract some of the incident light

• Both reflection and refraction can occur

• The light is absorbed and no light remains after absorption

If a person is 10 cm away from a plane mirror, how far away is their image from them?

• 5 cm

• 10 cm

• 15 cm

• 20 cm
