  • Light - 763 Words Below there are three objects a mirror, a glass block and a prism, it shows and tells you underneath each of 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... 763 Words | 2 Pages

Seeing colors and shapes is second nature to us, yet light is a perplexing phenomenon when we study it more closely. Here are some things to think about: Our brains and eyes act together to make extraordinary things happen in perception. Movies are sequences of still pictures. Magazine pictures are arrays of dots. Light acts like particles—little light bullets—that stream from... 385 Words | 2 Pages

  • LIght - 757 Words Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm), or 400×10−9 m, to 700 nanometres – between the infrared, with longer wavelengths and the ultraviolet, with shorter wavelengths. These numbers do not represent the absolute limits of human vision, but the approximate range within which most people... 757 Words | 3 Pages

  • Photosynthesis and Green Light Bulb Photosynthesis 1. Would you illuminate your house plants with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd, the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If... 386 Words | 1 Page

All sounds are vibrations traveling through the air as sound waves. Sound waves are caused by the vibrations of objects and radiate outward from their source in all directions. A vibrating object compresses the surrounding air molecules (squeezing them closer together) and then rarefies them (pulling them farther apart). Although the fluctuations in air pressure travel... 637 Words | 3 Pages

Besides his empirical explanation, where he observes that for the supposed motion of light to go “unnoticed from where the sun rises to where it sets is asking too much” (418b26), he also provides an argument that is understood through the “light of reason.” (418b24) To understand his contention we must refer to his definitions of light and the transparent. The transparent is, for Aristotle, the medium of sight; it is... 1,169 Words | 3 Pages
