Microscopy | Types Of Microscopy | Class 11 | Chapter 3 | Lecture 3 | Biology New Book 2025

Описание: 🔬 Class 11 Biology – Chapter 03: Cell and Sub-cellular Organelles
📚 Topic: Microscopy | Light & Electron Microscope (TEM & SEM)

In this video, we explore the concept of microscopy and the different types of microscopes used in biology, including Light Microscopes and Electron Microscopes (Transmission Electron Microscope - TEM, Scanning Electron Microscope - SEM).

👁️ Topics Covered in this Video:

▶ What is Microscopy?
▶ Human Eye Range & Cell Size
▶ Introduction to Microscopes
▶ Light Microscope: Parts, Working Principle, Magnification, Resolving Power
▶ Electron Microscope: How it Works, Types (TEM & SEM), Internal vs Surface Detail
▶ Diagrams of Light Microscope, TEM & SEM
▶ Comparison of Light and Electron Microscopes

📈 Magnification & Resolution Explained

▶ Light Microscope: 1500X magnification, 0.2 µm resolution
▶ Electron Microscope: Up to 1,000,000X magnification, 0.2 nm resolution

🧪 Fun Fact: Electron microscopes can view the internal structure of cells and create 3D surface images using metal-coated samples!
