Specular Reflection

Mr. Andersen explains specular reflection, where light reflects off a smooth surface like a mirror, maintaining the angle of incidence equal to the angle of reflection. He contrasts this with diffuse reflection, which occurs on irregular surfaces, scattering light in various directions. Using examples like a still lake and a PhET simulation, he illustrates how virtual images form and how surface irregularities like waves or snow affect reflection.

What is the key characteristic of specular reflection?

• The angle of incidence equals the angle of reflection.

• Light scatters in multiple directions.

• Light is absorbed by the surface.

• The surface must be rough.

Which of the following is NOT a possible outcome when light moves from one medium to another?

• Absorption

• Amplification

• Reflection

• Transmission

How does light behave when it hits a non-smooth surface like paper?

• It creates a virtual image.

• It scatters in multiple directions.

• It is completely absorbed.

• It reflects in a single direction.

What happens to the reflection when waves are added to a water surface?

• The reflection becomes more mirror-like.

• The reflection becomes diffuse.

• The reflection disappears completely.

• The reflection becomes brighter.

What type of reflection occurs on a snowy surface?

• Specular reflection

• Diffuse reflection

• Partial reflection

• No reflection
