PHY 205 Lecture Notes - Lecture 37: Electromagnetic Spectrum, Optical Fiber, Endoscope
Document Summary
Waves that require no material medium in which to travel. They carry energy as variations in the magnetic and electric fields in space. The family of em waves, ranging from radio waves to gamma and cosmic waves. Extremely small particle carrying negative charge and making up the outer shell(s) of an atom. A fibre optic device used to image the inside of living bodies as a diagnostic tool. Energy exists in many forms - heat, light etc; it is required to do work. The process by which liquids change into gases. In springs this is increased in length by applying a force to stretch the string. Referring to unstable materials; something that can readily be split it will split spontaneously. When a force is applied to a body it will cause a change in the state of motion of the body, making it accelerate, decelerate or change direction. Forces can also change the shape of an atom.
