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

intelligence is very difficult. Many theories have been posed as selective mechanisms for the trends toward increased intelligence in primate evolution. Some emphasize complex ecological pressures‚ mainly foraging strategies as the primary forces driving an evolutionary increases in cognitive abilities‚ and other suggest that increased social complexity favored the evolution of primate intelligence (Tomasello and Call‚ 1997). Across the animal kingdom‚ brain size increases with increasing body size‚ however

that small bird’s physical characteristics can greatly impact their population growth. The base line for this comparison will be two islands labeled island A and B with population A1 of finches on island A and a population of B1 finches on island B. There will be two time allotments used to factor in the population growth for each sets of populations on both islands: beginning with a 100 year scenario and then followed by a 200 year scenario. Using extended timelines will reflect accuracy in the
