Light Quiz

What are the two types of reflection?

• smooth reflection and rough reflection

• direct reflection and indirect reflection

• specular reflection and diffuse reflection

• regular reflection and irregular reflection

Define regular reflection.

• Reflection of light from a rough surface with equal angles of incidence and reflection.

• Reflection of light from a smooth surface with unequal angles of incidence and reflection.

• Refraction of light from a smooth surface with equal angles of incidence and reflection.

• Reflection of light from a smooth surface with equal angles of incidence and reflection.

Define diffused reflection.

• Reflection of light from a rough or irregular surface where the light rays are scattered in different directions.

• Reflection of light from a transparent surface where the light rays pass through without any scattering.

• Reflection of light from a polished surface where the light rays are absorbed.

• Reflection of light from a smooth surface where the light rays are scattered in different directions.

What is the law of reflection?

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

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

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

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

State the first law of reflection.

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

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

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

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

State the second law of reflection.

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

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

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

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

What is the angle of incidence?

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

• The angle of incidence is the angle between the normal to a surface and the reflected ray.

• 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 normal to a surface at the point of incidence.

What is the angle of reflection?

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

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

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

• The angle of reflection is always 90 degrees.

What is the normal in the context of reflection?

• A line that is diagonal to the surface at the point of incidence.

• A line that is tangent to the surface at the point of incidence.

• A line that is perpendicular to the surface at the point of incidence.

• A line that is parallel to the surface at the point of incidence.

What is the cornea?

• The cornea is the colored part of the eye.

• The cornea is a layer of muscle in the eye.

• The cornea is the transparent front part of the eye.

• The cornea is a type of lens in the eye.
