Questions and Answers
What happens to the angle of the reflected ray compared to the incident ray according to the reflection law?
What happens to the angle of the reflected ray compared to the incident ray according to the reflection law?
- The reflected ray has an angle equal to the incident ray. (correct)
- The reflected ray is always perpendicular to the surface.
- The reflected ray is always at a broader angle than the incident ray.
- The reflected ray is at a right angle to the incident ray.
How does the brain perceive light rays reflected by a mirror?
How does the brain perceive light rays reflected by a mirror?
- As originating from the mirror surface.
- As progressing further than they actually do. (correct)
- As bending around objects.
- As traveling in a straight line.
When light travels from an optically denser substance to an optically thinner substance, what occurs?
When light travels from an optically denser substance to an optically thinner substance, what occurs?
- The light ray refracts towards the vertical.
- The light ray is absorbed completely.
- The light ray reflects at the same angle.
- The light ray refracts away from the vertical. (correct)
Which statement correctly describes refraction when moving from an optically thinner medium to a denser medium?
Which statement correctly describes refraction when moving from an optically thinner medium to a denser medium?
Which of the following statements about the incident ray and reflected ray is true?

Study Notes
Reflection Law
- The incident ray, reflected ray, and normal all lie in the same plane.
- The angle of incidence (α) is equal to the angle of reflection (β).
- The path of the light ray can be represented graphically using a ray diagram.
- When light rays are reflected by a mirror, our brain perceives them as continuing in a straight line.
Refraction Law
- Refraction occurs when light passes from one medium to another.
- When light passes from a denser medium to a less dense medium, it is refracted away from the normal.
- When light passes from a less dense medium to a denser medium, it is refracted towards the normal.
