Reflection

What is reflection?

• The bending of light
• The bouncing back of light
• The absorption of light
• The stopping of light

Which surface is best for reflection?

• A rough wall
• A piece of paper
• A mirror
• A carpet

What is the name of the line drawn perpendicular to the reflecting surface?

• Incident ray
• Reflected ray
• Normal
• Refraction line

What is the angle of incidence?

• The angle between the incident ray and the reflecting surface
• The angle between the incident ray and the normal
• The angle between the reflected ray and the normal
• The angle between the reflected ray and the reflecting surface

What is the angle of reflection?

• The angle between the incident ray and the reflecting surface
• The angle between the incident ray and the normal
• The angle between the reflected ray and the normal
• The angle between the reflected ray and the reflecting surface

According to the law of reflection, the angle of incidence is __________ the angle of reflection.

• Greater than
• Less than
• Equal to
• Unrelated to

Which of the following is an example of regular reflection?

• Light reflecting off a mirror
• Light reflecting off a piece of paper
• Light reflecting off a wall
• Light reflecting off water with waves

What happens to light during diffuse reflection?

• It bounces off in one direction.
• It scatters in many directions.
• It is absorbed completely.
• It stops moving.

What is the incident ray?

• The ray of light that bounces off a surface
• The ray of light that travels toward a surface
• The line perpendicular to the surface
• The ray of light that is absorbed by the surface

What is the reflected ray?

• The ray of light that bounces off a surface
• The ray of light that travels toward a surface
• The line perpendicular to the surface
• The ray of light that is absorbed by the surface
