Plane Mirror Reflection Worksheet

A student looks at her reflection in a plane mirror and notices that when she raises her right hand, the image raises its left. What property of the image does this observation describe?

• The image is inverted top to bottom.

• The image is laterally inverted.

• The image is diminished in size.

• The image is virtual and real at the same time.

If the angle of incidence of a light ray striking a plane mirror is 35°, what is the expected angle of reflection?

• 55°

• 35°

• 45°

• 70°

A ray of light hits a mirror at 25° from the normal and reflects. Which statement best explains why the reflected ray also makes a 25° angle?

• The mirror bends the light by a fixed amount.

• The surface absorbs half the light and reflects half.

• The angle of reflection always equals the angle of incidence.

• The normal line changes depending on the surface.

Two mirrors are placed at a right angle (90°) to each other. When a light ray strikes one mirror, it reflects to the second mirror and then back toward the source. Which principle explains this?

• Multiple reflection following the laws of reflection

• Refraction of light through two media

• Dispersion of light through mirrors

• Total internal reflection

Which of the following best describes the image formed by a plane mirror?

• Real, inverted, and smaller than the object

• Virtual, upright, and same size as the object

• Real, upright, and magnified

• Virtual, inverted, and larger than the object

When you see the word AMBULANCE reversed on the front of an ambulance, what scientific principle allows drivers to read it correctly in their mirrors?

• Light scattering

• Diffuse reflection

• Lateral inversion

• Refraction

How do the two laws of reflection help in designing optical instruments such as periscopes?

• They ensure that the mirrors produce real images.

• They guarantee that light reflects predictably at equal angles.

• They cause light to bend instead of reflecting.

• They make images appear magnified.

Which everyday situation best illustrates the law of reflection?

• A spoon showing a distorted face image

• A flashlight beam bouncing off a mirror at the same angle

• Light bending when it enters water

• The sky appearing blue during the day

Why is understanding reflection of light in plane mirrors important in daily life?

• It helps us predict how objects will move.

• It allows us to see objects directly behind us using mirrors.

• It explains why light changes color through glass.

• It teaches how to bend light through lenses.

A driver checks the rear-view mirror before changing lanes. How does the reflection of light in the plane mirror make this possible, and why is it important for road safety?

• The mirror forms a real image, helping the driver see the exact distance of vehicles behind.

• The mirror reflects light at predictable angles, allowing the driver to see objects behind without turning around.

• The mirror refracts light so that the driver can see both near and far objects clearly.

• The mirror magnifies the image, making vehicles appear closer than they really are.
