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….
