Light – Reflection and Refraction — Science STD 10 — Question

CBSE BoardEnglish MediumSTD 10ScienceLight – Reflection and Refraction1 Mark
MCQ
In case refraction of light through a glass slab :
  • A
    Angle of incidence is equal to angle of refraction.
  • B
    Angle of refraction is equal to angle of emergence.
  • ✓
    Incident ray is parallel to emergent ray.
  • D
    Incident ray is parallel to refracted ray.
✓

Answer

Correct option: C.
Incident ray is parallel to emergent ray.
The incident ray and the emergent ray are parallel to each other. The light ray enters the slab from air which is why it bends towards the normal. In the case of emergent ray, the same refracted ray exits the slab into air, hence moving away from the normal. If we produce the incident ray, we can find that it is parallel to the emergent ray.
