Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

up to its name‚ the larvae from this plate did not contract as we increased the MRR‚ and continued to move. Although the number of waves per larva was different‚ it was higher than the waves produced in Table 2‚ the ChR2+ group. Larvae from this plate contracted immediately when the light was turned on and only produced waves during the interval the light was not on. Because the light flashed a set amount of times per second‚ the larva was not able to complete a full wave. This became more evident

Radio waves and Microwaves Radio communications Radio waves are used to broadcast radio or television signals from transmitters‚ which are then converted into electrical signals with an aerial (which is made out of metal to absorb the radio waves) so you can hear and see them. When done so the aerial converts this wave into an electrical signal (because of the electromagnetic waves energy exciting particles in the aerial and causing them to oscillate/vibrate and thus create an electrical current)

had events occurred differently‚ the whole direction of the war‚ and the result‚ might have differed. It is my opinion that the Battle of the Somme is the most crucial turning point of WW1. This might seem like a strange choice‚ given that this battle‚ above all‚ seems to represent the disastrous stalemate that locked the western front for most of the war. However in this essay I will argue that the Battle of the Somme achieved its central purpose‚ and began the inevitable decline and eventual defeat

Uses of Electromagnetic Waves Radio Waves * TV and FM radio (short wavelength) * Direct line of sight with transmitter (do not diffract) * Medium wavelength – travel further because they reflect from layers in the atmosphere * Used for transmitting signals. Microwaves * Microwaves are used in satellite television broad casting. * It is used to transmit mobile phone signals between Mast‚ which may be up to 20km apart. * Microwaves are absorbed by water molecules

world. The Wave by Morton Rhue and the poem “The Door” by Miroslav Holub are the two examples which focus on proving the effect that environment‚ relationships and experiences have on the individual and their world. Body: The environment that people live in has a huge impact on people. The environment is the world they live in. It changes people in both positive and negative ways. The Wave‚ for instance‚ shows how the individual and their world are affected by the setting. Before the wave was introduced
