Law of Reflection of Light Quiz

What is the incident angle?

• Angle between the incident ray and the reflected ray

• Angle between the incident ray and the surface

• Angle between the reflected ray and the normal to the surface

• Angle between the incident ray and the normal to the surface

How is the incident angle related to the normal line?

• The incident angle is the angle between the incident ray and the normal line.

• The incident angle is unrelated to the normal line

• The incident angle is perpendicular to the normal line

• The incident angle is always greater than the normal line

What is the formula to calculate the incident angle?

• incident angle = angle of incidence

• incident angle = 90 degrees

• incident angle = angle of refraction

• incident angle = angle of reflection

What is the reflected angle?

• The angle between the reflected ray and the surface

• The angle between the reflected ray and the normal to the surface at the point of incidence.

• The angle between the reflected ray and the refracted ray

• The angle between the reflected ray and the incident ray

What is the normal line in the context of reflection of light?

• A line that is at a 45-degree angle to the surface at the point where the light ray strikes the surface.

• A line that is at a 90-degree angle to the surface at the point where the light ray strikes the surface.

• An imaginary line that is perpendicular to the surface at the point where the light ray strikes the surface.

• A line that is parallel to the surface at the point where the light ray strikes the surface.

How does the normal line relate to the incident and reflected angles?

• It creates a 90-degree angle with the incident and reflected angles.

• It has no relation to the incident and reflected angles.

• It doubles the incident and reflected angles.

• It bisects the incident and reflected angles.
