discovered. By the early 19th century‚ evidence that light is a wave had grown very persuasive. In 1873‚ James Clerk Maxwell predicted the existence of electromagnetic waves and calculated their speed of propagation. This development‚ along with the experimental work of Heinrich Hertz starting in 1887‚ showed conclusively that light is indeed an electromagnetic wave. The wave picture of light is not the whole story‚ however. Several effects associated with emission and absorption of light reveal a particle

building blocks which make stuff. Bosons are units of force. Bosons are the mechanisms of interaction and exchange. There are four different types of forces in the Standard Model: electromagnetic force‚ the strong force‚ the weak force and gravity. The electromagnetic force explains electricity‚ magnetism‚ and other electromagnetic waves including light and it is carried by the photon. The strong force holds quarks together to make hadrons such as protons and neutrons. The weak force keeps atoms together

Abstract This paper is an evaluative look at why the Chevrolet Corvette is one of the greatest sports cars in the world. Sports cars can be judged in three areas; cost‚ performance‚ and comfort‚ each area will be evaluated as to why these criteria are important‚ with examples shown to for definition. The Corvette will be shown how it compares in regards to the measurements‚ and in some cases exceeds them. Showing why it should be considered a great sports car The Chevrolet Corvette: A great sports

Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like

energy transformation is a change in the type of energy‚ for example a change from sound energy to electromagnetic waves. Relating this to the mobile telephone‚ it undergoes basic energy transformations of‚ sound wave (your voice)‚ to electrical energy (in the wires inside the phone)‚ to electromagnetic waves (from the phone to the tower)‚ to electrical energy (at the tower)‚ then to electromagnetic waves (to reach the receiving phone)‚ then electrical energy (inside the receiving phone)‚ then to

Newton’s Laws of Motion and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that
