The resolving power of an electro microscope is higher than that of an optical microscope because the wavelength of electrons is `"________________"` than the wavelength of visible light.

Explanation

To solve the question, we need to understand the relationship between the resolving power of microscopes and the wavelengths of the light or particles they use. Here’s a step-by-step breakdown:

### Step 1: Understand Resolving Power
Resolving power is the ability of an optical instrument to distinguish between two closely spaced objects. The higher the resolving power, the better the instrument can resolve detail.

### Step 2: Relate Resolving Power to Wavelength
The resolving power (R) of a microscope is inversely related to the wavelength (λ) of the light or particles used. This can be expressed as:
\[ R \propto \frac{1}{\lambda} \]
