What type of reflection occurs on smooth, glossy surfaces like mirrors?

Specular reflection.

Answer in your head, out loud, or on paper, then tap the card to flip.

In specular reflection, how do the incoming rays reflect off the surface?

The incoming rays reflect off at the same angle, giving a clear image.

Answer in your head, out loud, or on paper, then tap the card to flip.

What type of reflection occurs on rough surfaces?

Diffuse reflection.

Answer in your head, out loud, or on paper, then tap the card to flip.

In diffuse reflection, how do the incoming rays reflect off the surface?

The incoming rays get scattered in many directions rather than a single direction.

What is the law of reflection?

When light reflects off a surface, the angle of incidence equals the angle of reflection.

What is the angle of incidence?

The angle of incidence is the angle between the incident (incoming) ray and the normal.

What is the angle of reflection?

The angle of reflection is the angle between the reflected ray and the normal.

Is a mirror an example of a surface that causes specular or diffuse reflection?

A mirror is an example of a surface that causes specular reflection.

Answer in your head, out loud, or on paper, then tap the card to flip.

Is a rough surface more likely to cause specular or diffuse reflection?

A rough surface is more likely to cause diffuse reflection.

Answer in your head, out loud, or on paper, then tap the card to flip.

In which direction do incoming rays scatter when undergoing diffuse reflection?

In diffuse reflection, incoming rays scatter in many directions rather than a single direction.

Answer in your head, out loud, or on paper, then tap the card to flip.

What is the perpendicular line called in relation to the law of reflection?

The perpendicular line is called the normal in relation to the law of reflection.

Answer in your head, out loud, or on paper, then tap the card to flip.

What is the key difference between specular and diffuse reflection?

In specular reflection, incoming rays reflect at the same angle, giving a clear image. In diffuse reflection, incoming rays scatter in many directions, not giving a clear image.
