Reflection & Refraction
State the law of reflection (angle of incidence = angle of reflection) and explain refraction as the change in speed and direction when light crosses a boundary between two media; apply ray diagrams for plane mirrors and refracting surfaces

Question 1 of 3
A ray of light traveling in air strikes a plane mirror. The angle of incidence measured from the normal is 30°. What is the angle between the incident ray and the reflected ray?
Question 2 of 3
The speed of light in air is approximately 3.00 × 10⁸ m/s. In a certain transparent liquid the speed of light is 2.25 × 10⁸ m/s. What is the index of refraction of the liquid?
Question 3 of 3
A ray of light travels from air (refractive index = 1.00) into glass (refractive index = 1.50). If the angle of incidence in air is 30°, what is the angle of refraction in the glass?
