MCQ
Physical processes are sometimes described visually by lines. Only the following can cross.
- AStreamlines in fluid flow
- BLines of forces in electrostatics
- ✓Rays in geometrical optics
- DLines of force in magnetism
✓
Answer
Correct option: C.
Rays in geometrical optics
c
$(c)$ Rays can cross-each other while forming image etc.
$(c)$ Rays can cross-each other while forming image etc.
- Light rays are path of light waves and two waves can cross without effecting each other's characteristics.
- In streamline flow different layers of flowing fluid does not mix with each other. So, streamlines never crosses in entire flow.
- Electric field lines and magnetic field lines never cross as there is only one direction of field at a point in space.
