There are two contrasting views that light either consists of particles or waves. Light is a perplexing phenomenon puzzled by Ancient Greeks and scientists for years. Even Issac Newton developed incorrect theories on light‚ when he was the inventor and genius behind physics. It has been proved that light can be both a particle and a wave. Human eyes collect light that is reflected from a source. For example‚ the light from a pencil comes from the source of light in the sun and travels to the pencil

Biomechanical principles are what introduces the human body to motion‚ so the tennis biomechanics is essentially the science mechanics tennis technique. Tennis is a game in which two or more players hit the ball with rackets over a low net that is stretched across a court which is usually artificial surface. The tennis serve begins from the feet hitting the ground then continues up through the torso to the shoulders‚ then moves to the arm and then wrist. It continues right to the point when the ball

Energy: the ability to do work. Work= force x displacement. Power=energy/time Power is measured in watts or horsepower. Joules/sec=watts 1hp=746w=1kw Basal metabolic rate 2000kcal/day= 100w Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form‚ Efficieny- e.motor=85%‚ combustion= 20% Hydrogen is not a source of energy but a means of transportation Types of energy:

Mathematical physics is the study of mathematical systems that stands for physical phenomena. Mechanics deals with the behavior of objects and systems in response to various forces. Molecular physics examines the structure‚ properties‚ and behavior of molecules. Nuclear physics is concerned with the structure and properties of the atomic nucleus

Application of Normal mode calculations in optical spectroscopy | Phym 221 – Assignment 4 1. Introduction Normal modes are used to describe the different vibration motion in molecules. There are different types of modes for molecules in different motions and each has a certain symmetry associated with it. 2. Overview of Normal Modes Generally‚ normal modes are independent atoms in a molecule that are in motion such that they do not disturb the motion of the other molecules. Normal modes

properties can be derived from first principles without recourse to particle or wave mechanics. The approach‚ which is referred to as guided-wave mechanics‚ is based on the kinematics of photon propagation rather than field modes‚ the latter tending to obscure the underlying mechanics. As a consequence‚ concepts that appear as postulates in traditional relativistic quantum mechanics appear in guided-wave mechanics as derived quantities with physically intuitive‚ albeit novel‚ interpretations.
