Observation:
- Angle of incidence: 30 degrees
- Angle of emergence: 20 degrees
- Difference between angle of incidence and angle of emergence: 10 degrees

Explanation:

Refraction of light through a glass slab:
- When light passes from one medium to another, it changes its direction due to the change in the speed of light.
- The angle at which the light ray enters the glass slab is called the angle of incidence.
- The angle at which the light ray emerges from the glass slab is called the angle of emergence.

Angle of incidence:
- The angle of incidence is the angle between the incident ray and the normal to the surface of the glass slab at the point of incidence.
- In this activity, the angle of incidence was measured to be 30 degrees.

Angle of emergence:
- The angle of emergence is the angle between the emergent ray and the normal to the surface of the glass slab at the point of emergence.
- In this activity, the angle of emergence was measured to be 20 degrees.

Difference between angle of incidence and angle of emergence:
- The difference between the angle of incidence and angle of emergence is called the angle of deviation.
- In this activity, the difference between the angle of incidence (30 degrees) and angle of emergence (20 degrees) was found to be 10 degrees.
