Drawing Ray Diagrams
Draw ray diagrams to show reflection at a plane mirror (angle of incidence = angle of reflection) and refraction at a boundary between media; use ray diagrams to locate images and explain how lenses and mirrors work

Question 1 of 3
A ray of light strikes a mirror at 20° to the normal, as shown in the ray diagram. What is the angle between the reflected ray and the surface of the mirror?
A ray diagram: a light ray strikes a flat mirror at point O. A dashed normal is drawn perpendicular to the mirror. The incident ray meets the normal at 20 degrees; the reflected ray leaves on the other side of the normal.
Question 2 of 3
A ray of light strikes a mirror at 60° to the normal, as shown in the ray diagram. What is the angle between the incident ray and the reflected ray?
A ray diagram: a light ray strikes a flat mirror at point O. A dashed normal is drawn perpendicular to the mirror. The incident ray meets the normal at 60 degrees; the reflected ray leaves on the other side of the normal.
Question 3 of 3
A ray of light strikes a mirror at 25° to the normal, as shown in the ray diagram. What is the angle between the incident ray and the reflected ray?
A ray diagram: a light ray strikes a flat mirror at point O. A dashed normal is drawn perpendicular to the mirror. The incident ray meets the normal at 25 degrees; the reflected ray leaves on the other side of the normal.
