disadvantages of a light microscope and electron microscope? Some of the disadvantages of the light microscope include‚ that since it send light‚ the light waves are diffracted as they pass through the matter. Because of this‚ light microscopes can only produce clear images of objects to a magnification of about 1000 times. Another problem is that since most living cells are nearly transparent‚ you can’t see them. So you have to use dyes to stain them. The advantage of using a light microscope however

lesson‚ you need to know a little bit about light. White light consists of all the colors of the rainbow mixed together. Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics‚ the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Isaac Newton thought that light must be a particle because particles of light that travels in straight lines until they are

THE NATURE OF LIGHT Until the time of Isaac Newton (1642–1727)‚ most scientists thought that light consisted of streams of particles (called corpuscles) emitted by light sources. Galileo and others tried (unsuccessfully) to measure the speed of light. Around 1665‚ evidence of wave properties of light began to be discovered. By the early 19th century‚ evidence that light is a wave had grown very persuasive. In 1873‚ James Clerk Maxwell predicted the existence of electromagnetic waves and calculated

the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into a series of colours. This shows that white light is actually made up of many other colours - a fact first

of Light on Snapdragon Flowers Introduction: It is a well-known fact that plants need light for nourishment‚ yet many people are ignorant of the reasons behind this.
