CH110 Chapter 7: CH110 - Chapter 7 (The Quantum Mechanical Model of the Atom)
Document Summary
Electromagnetic radiation (cid:314) a form of energy propagated as mutually perpendicular electric and magnetic fields through a vacuum or through a medium (such as glass) Includes visible light, infrared, ultraviolet, x-ray, and radio waves. Ave (cid:314) a disturbance that transmits energy through a medium. Example (cid:314) traveling wave in a rope; as a result of up-and-down hand motion, waves pass along the rope from left to right continuing for the entire length of the rope. Trough (cid:314) low points; the greatest depth below the centre line. Crest (cid:314) high points; the greatest height above the centre line. Amplitude (cid:314) the height of a crest/depth of a trough from the centre line. Avelength ((cid:540)) (cid:314) the distance between successive crests or troughs of a wave motion. Frequency (v) (cid:314) in wave motion, this is the # of wave crests or troughs that pass through a given point in a unit of times (unit (cid:314) time-1, hz is equivalent to s-1)
