. (essay) In many of the imaging processes, e.g. the microscope and the electron microscope, the resolution is limited by the wavelength of the light or the matter to a size scale comparable to the wavelength. Explain why this method of obtaining a 3D image gives an image with resolution that is much smaller than the 300 m wavelength of these radiowaves

Solution

In 3d imaging process light beam is replaced by a fast moving electrons. The wavelength of these fast moving electrons are about 10,000 times smaller than the visible light used. These technique involves the processes like refraction and diffraction in which the size of the object is comparable to the wavelength of the incident beam.
