Use the ray diagram of light reflecting from a plane mirror. What is the angle of reflection θ?
In the figure, the marked 25 degrees is between the incident ray and the mirror surface, not the normal. What is the angle of reflection?
The diagram marks the angle of incidence as 48 degrees from the normal. What is the angle of reflection?
A ray is drawn 70 degrees from the mirror surface. What is the angle of reflection?
Use the ray diagram of light reflecting from a plane mirror. What is the angle of reflection θ?
The marked 40 degrees is the angle between the incident ray and the mirror surface. What is the angle of reflection?
A ray strikes a plane mirror at 62 degrees from the normal. What angle should the reflected ray make with the normal?
A ray of light travels along the normal into a plane mirror. What is the angle of reflection?
The diagram shows an incident ray only 10 degrees above the mirror surface. What is the angle of reflection?
Use the ray diagram. The angle of incidence is 75 degrees. What is the angle of reflection?
The ray diagram shows four possible outgoing rays. Which labeled candidate is the reflected ray?
A ray hits a plane mirror at 50 degrees from the normal. Which candidate path follows the law of reflection?
Look at the candidate rays. Which one gives the correct reflected path for the incident ray?
The incident ray is marked 65 degrees from the normal. Which labeled outgoing ray is correct?
Which candidate ray is the proper reflection of the incident ray shown in the diagram?
A plane mirror is struck by the ray in the diagram. Which labeled candidate is the reflected ray?
The incoming ray is close to the normal. Which candidate outgoing ray is physically correct?
Which candidate path shows the reflected ray when the incident ray is 70 degrees from the normal?
The figure shows an arrow object 40 cm in front of a plane mirror. Where is its image, and what is it like?
An object is 1.2 m in front of the plane mirror in the figure. Which description matches the image?
The object in the figure is 25 cm from a plane mirror. What image would an observer see?
A small object is 0.75 m in front of the plane mirror shown. Which statement correctly locates its image?
The ray diagram shows a 3.0 m object distance to a plane mirror. Which image description is correct?
An arrow is 18 cm from a vertical plane mirror in the figure. What happens to the image?
Which statement is the law of reflection for a plane mirror?
What is the normal line in a reflection diagram?
A laser beam shines on rough white paper, and light scatters in many directions. What is true of each tiny reflection?
Why does a polished plane mirror form a clear image while notebook paper does not?
What does it mean that a plane-mirror image is virtual?
Which description of a plane-mirror image is correct?
A light ray strikes a plane mirror at 35 degrees from the normal. What is the angle between the incident ray and the reflected ray?
A ray makes a 60 degree angle with a mirror surface. What is its angle of incidence?
When you see a pencil in a flat mirror, where does the light actually travel?
Crumpled aluminum foil scatters light in many directions and gives a blurry reflection. What is this kind of reflection called?
A student is 1.80 m tall, with eyes 0.10 m below the top of the head. What is the shortest plane mirror that lets the student see head to toe?
A person 1.60 m tall has eyes 1.48 m above the floor. For a full-body plane mirror, how high above the floor should the bottom edge be?
An object stands 2.0 m in front of a plane mirror. How far is the object from its image?
A student is 2.0 m from a plane mirror, then walks 0.50 m closer. By how much does the distance between the student and the image change?
Let positions in front of a plane mirror be positive and positions behind it be negative. If an object is at +30 cm, where is its image?
A 1.70 m student wants a full-length plane mirror. If the student steps farther from the mirror, what happens to the shortest mirror height needed?
