the circuit: Light Dependent Resistors Light Dependent Resistors (LDR) are also called photoresistors. They are made of high resistance semiconductor material. When light hits the device‚ the photons give electrons energy. This makes them jump into the conductive band and thereby conduct electricity. A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other

a moment of pause in the air and the scene was different than before when the light had turned red. The blurred surroundings I have seen only a few seconds ago gradually cleared up and I could now see the busy people walking outside.

Part I. Question 1 Aristotle uses two methods to prove light cannot travel. 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 “what

Since only the very top of the ocean receives light from the sun‚ animals have difficulty using their eyes to find their way around in deeper waters. Once animals dive‚ they rely heavily on their hearing to sense their environment. In this essay I’m going to answer these questions by explaining in turn what light and sound are‚ but first we need to know what waves are in order to make it easy to understand the others. Waves exist in both sound and light. Or to make a better sense‚ it is what makes

Without color or light‚ art would be nothing; we wouldn’t be able to see or distinguish anything. Light allows us to see the space about something; when it casts a shadow on something we know the size of something. Without color we wouldn’t be able to differentiate between anything. It allows us to see the edges of something which in turn allows us to form the relationships in size and space. Colors can also be used to accomplish a diverse sense of feelings. For example‚ artists can use colors to
