Reflection of Waves Quiz

What are the three things that can happen when a wave arrives at a boundary between two materials?

• Reflection, Refraction, Diffusion

• Absorption, Refraction, Diffusion

• Absorption, Transmission, Reflection

• Transmission, Refraction, Diffusion

What is the term used when a wave is absorbed by a material?

• Reflection

• Transmission

• Absorption

• Refraction

During a science experiment, Mia and Daniel observed a wave passing through a glass window. What happens to the wave during transmission?

• It is reflected off the surface

• It is scattered in different directions

• It is absorbed by the material

• It enters the material and passes out the other side

David is playing with a mirror and a flashlight. What is the rule for the angle of incidence and the angle of reflection?

• The angle of incidence is always perpendicular to the angle of reflection

• The angle of incidence is always less than the angle of reflection

• The angle of incidence is always equal to the angle of reflection

• The angle of incidence is always greater than the angle of reflection

Harper is using a laser pointer to demonstrate how light reflects off a mirror. What is the normal in this ray diagram?

• A line at 90 degrees to the incoming ray

• A line at 45 degrees to the surface

• A line perpendicular to the surface

• A line parallel to the surface

What is the point called where the incoming ray touches the boundary?

• Point of refraction

• Point of reflection

• Point of incidence

• Point of transmission

Mia is looking at herself in a perfectly smooth mirror. What type of reflection occurs on the mirror's surface?

• Normal reflection

• Scattered reflection

• Specular reflection

• Diffuse reflection

Charlotte and Noah were trying to see their reflections in a piece of paper. Why couldn't they see their reflections?

• Because the paper transmits all the light

• Because the paper is too thin

• Because the paper reflects light in all different directions

• Because the paper absorbs all the light

During a science experiment, Lily noticed that light hitting a rough surface scattered in many directions. What is the term for this type of reflection?

• Scattered reflection

• Normal reflection

• Diffuse reflection

• Specular reflection

David is shining a flashlight on a mirror and a wall. In both cases, what remains true about the angles of incidence and reflection?

• The angle of incidence is always less than the angle of reflection

• The angle of incidence is always greater than the angle of reflection

• The angle of incidence is always equal to the angle of reflection

• The angle of incidence is always perpendicular to the angle of reflection
