An electron microscope is a device based on the wave nature of an electron.

For an object to be visible to us, its size must be greater than the wavelength of the light used. Therefore, visible light (400-700 nm) cannot be used to see objects as large as the nanometer range.

But it is possible with electrons. Using Debroy’s equation, electron beams of the required wavelength can be generated. It detects the reflected beam sent to the object. So let’s create an image of the object.
