Compare and contrast the use of light and electron microscopes in biological studies. Microscopes are laboratory equipment which are used to observe any matter that is too small to be seen by the naked eye. There are several types of microscopes – the two most common being the optical microscope‚ also known as a light microscope‚ and the electron microscope‚ which can be either a transmission electron microscope (TEM) or a scanning electron microscope (SEM). There are more differences than similarities

What is light produced‚ reflected and refracted into visible light? Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The definition of produced visible light means when the electromagnets radiation meets the human eye. The first example of produced is a glow stick because it produces its own light . Another
