The invention of the microscope was a great boon for people to study smaller objects or micro-organisms. Scientists made different microscopes by using different types of lenses for magnification.
Gaurav made a table of two scientists and the kind of microscope they invented.
| The kind of microscope | Scientist |
|---|---|
| P | Robert Hooke |
| Q | Antony Van Leeuwenhoek |
Identify P and Q
- P — Simple microscope, Q — Compound microscope.
- P — Electron microscope, Q — Simple microscope.
- P — Compound microscope, Q — Electron microscope.
- P — Compound microscope, Q — Simple microscope.
P — Compound microscope, Q — Simple microscope.
Reason — Compound microscope was invented by Robert Hooke and simple microscope was invented by Antony Van Leeuwenhoek.
Key Concepts Covered
