Refractive Index: Refractive Index formula is use to find the change of speed of light as it travels from air into glass. It measure how much light slows down when it enters denser medium such as glass. The formulae is written as: To find out the refractive index‚ substitute these into the equation; The speed of light travels in air is 3 x 10^8-1 The speed of light travels in glass is 2 x 10^8 ms^-1 Refractive Index (Glass): 3 x 10^8 / 2 x 10^8 = 1.5 When light enters glass‚ its reflective index is 1

sensitive is Db to s? To N? Db is the particular measure of species richness and it decreases when s (the number of different species) decreases. Db decreases when N (the number of individuals) increases. 2. How s and N affect the Simpson Index? Simpson Index is a measure of diversity which takes into account the number of species present‚ as well as the relative abundance of each species. In this case‚ a few rare species (s) with only a few representatives (N) will not affect the diversity. 3

The Ankle Brachial Pressure Index is a test that demonstrates the cardiovascular status of the lower limb. It is a quick‚ noninvasive way to check for risk of peripheral artery disease (PAD). Peripheral artery disease is a condition in which the arteries in the legs or arms are narrowed or blocked. People with peripheral artery disease are at an increased risk of heart attack‚ stroke‚ poor circulation and leg pain. If the foot pulses can be clearly felt then the risk of vascular disease and associated

Aim:- To investigate the effect of changing the temperature of glycerin on the index of refraction. In this experiment I will be using a simple method‚ which needs the following materials 40ml of glycerin in a beaker‚ protractor‚ a pencil‚ a laser‚ a paper to draw boundaries‚ circular plastic plates‚ hotplate‚ ruler and a digital thermometer. In this experiment 1 trial will be conducted for glycerin with 70 Celsius degrees ‚66‚62‚58‚ and another trial with 10 Celsius degrees. Scientific Background:-

a) Power Distance Index Power Distance Index (PDI) refers to the degree of inequality that exists and is accepted between people with and without power. A high-PDI score indicates that a society accepts an unequal‚ hierarchical distribution of power‚ and that people understand “their place” in the system. A low-PDI score means that power is shared and widely dispersed‚ and that society members do not accept situations where power is distributed unequally (refer to figure 1.1.4). Application: According
