Answer 1) Compound Microscope.
Explanation : Compound microscope is the kind of optical microscope which creates a two dimensional image when the visible light is illuminated it magnifies the object and produces its image. It uses two kinds of lenses which are objective lens and the ocular lens.
Answer 2) Electron microscope.
Explanation : There are two types of electron microscope which are widely used SEM (Scanning Electron Microscope) and TEM (Transmission Electron Microscope). These type of microscope uses a beam of electrons which create an magnified image of the specimen. It has very higher magnification power and has a greater resolving power than a light microscope, which allows it to see much smaller objects in finer detail. This was the microscope which was used to study DNA molecules.
Answer 3) Scanning Electron Microscope.
Explanation : This is a kind of electron microscope which has the magnification ability of up to 60,000 times without losing clarity. It produces images of a sample simply by scanning the surface with a focused beam of electrons through a laser. The electrons interact with atoms in the sample, and produce various signals which contains information about the surface topography and composition of the sample.
Answer 4) Scanning Tunneling Microscope
Explanation : This is a kind of microscope which shows the arrangement of atoms on the surface of the molecules. A scanning tunneling microscope (STM) is an instrument for imaging surfaces at the atomic level. It allows the 3D pictures of the image to be created.
Answer 5) Transmission Electron Microscope.
Explanation : This kind of electron microscope uses a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most commonly an ultrathin section which is less than 100 nm thick or a suspension on a grid. It has the magnification power of hundreds of thousands of times.
