I. Introduction to Waves

Speed

a) V= fl

b) When a wave changes speed, its wavelength changes not its frequency

c) Loudness and brightness is determined by the amplitude of the wave

Wave Speed Rope

 v = (F_T /µ)^1/2

µ = mass/Length

F_T - Tension (N)

Speed depends on medium

Sound travels faster in solids, wavelength changes f doesn't

v = 340 m/s (Sound)

p. 302)  1,2

Ex) sound, water waves, light, microwaves, heat rays

2. Waves can be produced in two ways:

a. Vibration of particles

(requires a medium for transfer)

(mechanical wave)
