Question 1:

When light is reflected from a smooth surface, the angle of reflection is:

Explanation: According to the law of reflection, the angle of reflection is equal to the angle of incidence.

Question 2:

When light travels from a less dense medium to a more dense medium, it will:

Explanation: When light travels from a less dense medium to a more dense medium, it bends towards the normal.

Question 3:

Snell's Law describes the relationship between:

Explanation: Snell's Law describes the relationship between the incident angle and the refracted angle when light passes through the interface between two different mediums.

Question 4:

The refractive index of a medium is a measure of:

Explanation: The refractive index of a medium is a measure of how much light bends when it enters that medium.

Question 5:

When light is incident at an angle greater than the critical angle, it undergoes:

Explanation: When light is incident at an angle greater than the critical angle, it undergoes total internal reflection, meaning it is completely reflected back into the same medium.
