Divide the following fractions:
Here, we have to divide the given fractions.
Now, 2/11 ÷ 9/22
= 2/11 × 22/9
= 2/1 × 2/9
= 2 × 2 / 1 × 9
= 4/9
Hence, the correct option is (a).

During normal incidence on a glass slab, the angle of incidence = ____.
- When a ray of light falls on a glass slab normally, the angle between normal and incident ray is zero.
- Therefore, angle of refraction and emergence will also be zero.
- So, the correct option is c.

During refraction through a glass slab, when the medium at the both sides of the glass slab is the same then, the incident ray is parallel to ____.
- On both the parallel sides of the glass slab, the change in direction of light ray is equal but in opposite directions.
- Thus, the light ray emerging from the glass slab is parallel to the incident ray.
- So, the correct option is b.
