Inverse-square law

Experiment 1 Introduction: The aim of this experiment is to investigate the effect of the inverse square law on a beam of x-ray photons. The inverse square law states that the intensity of an x-ray beam is inversely proportional to the square of the distance (Ball, J.L., Moore, A.D. and Turner, S., 2008). Similar triangles (Appendix A- Image 1) are a proof of the inverse square law as it shows that if the distance from the beam is doubled, the intensity falls to one-quarter of its original value

The graphs and results above demonstrate that the inverse square law of distance and brightness to be satisfied inverse square law simply means that as the distance to the star increases, then the brightness will decrease. This table displays this because at 10,000 cm there was 17.3 lux of brightness on the light meter. Moreover, at the start at 100 cm there was a total of 532.0 lux of brightness and therefore this proves that the law of inverse square is established appropriately. The tables and the

Abstract: To investigate whether light intensity of incoherent lights varies inversely with the square of the distance holds true in real-life situations and under laboratory conditions. Techniques utilised in the experiment included measuring the distance from the light source to the light sensor, recording the light intensity of a light source and recording observations with accuracy. The light from the light source that passes through the cardboard cylinder tube changes as the distance from

- What features of the graph would you need for the expected proportionality to be verified? In other words, what should the graph look like to verify the inverse square law? (2 marks) The inverse square law states, that the intensity of the luminosity is inversely proportional to the square of the distance from the source. The graph would require features such as; evidence that the increase in distance away from the source results in the reduction of light exposure as well as, the contrast between

Determination of the Rate Law for the Bleaching of Blue One Objective The objective of this investigation is to determine how the concentrations of the reagents in the reaction between Blue One dye and Sodium Hypochlorite (bleach) will affect the rate for the reaction. This will be done by through the determination of the rate law with respect to the orders of reaction for the reagents as well as the overall order of the reaction. Introduction The question for this investigation came about when

Tycho Brahe. Inheriting the precise data Brahe collected after Brahe died, Kepler delineated his most famous discoveries--his three laws of planetary motion. Other than those three laws, he also made great contributions to the scientific field: he made discoveries in optics, gave explanations to the cause of tides on Earth, and invented logarithm.

Despite the fact that his mother was very well off he was entered as a sizar, a student who receives and allowance toward college expenses for acting as a servant to another student. Isaac's goal at Cambridge was a law degree. Education at Cambridge was dominated by the philosophy of Aristotle. He also studied the philosophy of Gassendi, Hobbes, Descartes, and Boyle. He was attracted to the mechanics of Coperican astronomy of Galileo. He also studied

philosopher who is famously known for his law of gravitation, his explanation on how gravity works, and his laws of motion,. Newton had a tremendous influence on the Scientific Revolution which occurred from the mid 1500’s to the early 1800’s. Newton was born January 4, 1643 in the town of Lincolnshire in the country of England. Newton’s infamous laws of motion were published in his literature, “Philosophiae Naturalis Principia Mathematica”, in 1687. Newtons first law of motion is, “Every object in motion
