The resolving power of electron microscope is

Options

A. 10
B. `10^(5)`
C. `100^(5)`
D. `1000^(5)`

Answer

To determine the resolving power of an electron microscope, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Resolving Power**:
- Resolving power refers to the ability of a microscope to distinguish between two closely spaced objects. A higher resolving power means that the microscope can distinguish smaller details.

2. **Differentiate Between Types of Microscopes**:
- There are two main types of microscopes: light microscopes and electron microscopes. Light microscopes use visible light to illuminate the specimen, while electron microscopes use a beam of accelerated electrons.

3. **Wavelength Comparison**:
- The wavelength of electrons is significantly shorter than that of visible light. Specifically, the wavelength of electrons is about 1000 times shorter than that of visible light. This shorter wavelength allows electron microscopes to resolve much smaller structures.

4. **Resolving Power of Electron Microscopes**:
- Due to the shorter wavelength of the electron beam, electron microscopes have a much higher resolving power compared to light microscopes. The resolving power of an electron microscope is typically around 10 Å (angstroms), which is equivalent to 10^-10 meters.

5. **Select the Correct Option**:
- Given the options provided (10, 10^5, 100^5, and 1000^5), the resolving power of the electron microscope is 10 Å. Thus, the correct answer is option A: 10.

### Final Answer:
The resolving power of an electron microscope is **10 Å**.
