In which of the following situations does the Law of Reflection apply?

• When light passes from one medium to another.

• When light is absorbed by a surface.

• When light bounces off a smooth surface.

• When light refracts through a convex lens.

What is the normal in the context of the Law of Reflection?

• A line that runs parallel to the reflected ray.

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

• A line that marks the angle of refraction.

• A line that connects the light source and the mirror.

If the angle of incidence is 30° in a plane mirror, what is the angle of reflection?

• 60°

• 30°

• 90°

• 45°

In the Law of Reflection, which of the following is true?

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

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

• The angle of reflection is always larger than the angle of incidence.

• The incident ray, reflected ray, and the normal always lie in the same plane.

What does the Law of Reflection state?

• Reflection only occurs when light strikes a convex surface.

• Light always bends when it strikes a surface.

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

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

What happens when light passes from a medium with a lower refractive index to a medium with a higher refractive index?

• The light bends away from the normal.

• The light bends toward the normal.

• The light refracts in a straight line.

• There is no change in the direction of light.

When does total internal reflection occur according to Snell's Law?

• When the angle of incidence is less than the critical angle.

• When the angle of incidence exceeds the critical angle.

• When light passes from a less dense to a denser medium.

• When light passes through a transparent medium.

What does Snell's Law describe?

• The relationship between the speed of light and the angle of incidence.

• The relationship between the angle of incidence and the angle of reflection.

• The relationship between the angles of incidence and refraction when light passes between two media.

• The bending of light when it strikes a surface.
