Light Quiz

What is reflection of light?

• The reflection of light is the absorption of light when it hits a surface.

• The reflection of light is the disappearance of light when it hits a surface.

• The reflection of light is the bouncing off of light when it hits a surface.

• The reflection of light is the bending of light when it hits a surface.

When light bounces off a surface, it is called?

• absorption

• transmission

• refraction

• reflection

What is the angle of incidence?

• The angle of incidence is the angle between the incident ray and the angle of reflection.

• The angle of incidence is the angle between the incident ray and the reflected ray.

• The angle of incidence is the angle between the incident ray and the transmitted ray.

• The angle of incidence is the angle between the incident ray and the normal to a surface at the point of incidence.

What is the angle of reflection?

• The angle of reflection is always 90 degrees.

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

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

• The angle of reflection is determined by the color of the object.

What is refraction of light?

• The reflection of light as it passes from one medium to another medium with a different refractive index.

• The absorption of light as it passes from one medium to another medium with a different refractive index.

• The scattering of light as it passes from one medium to another medium with a different refractive index.

• The bending of light as it passes from one medium to another medium with a different refractive index.

When light bends as it passes from one medium to another, it is called?

• refraction

• absorption

• diffraction

• reflection
