Unformatted text preview: PHYS 2101 I. Types of Waves II. Waves in Time III. Waves in Space IV. Speed of a Wave A. Speed of Propagation B. Transverse Speed V. Waves on a String Spring 2011 PHYS 2101 Do they need a medium to travel? Mechanical waves - need a medium examples: water waves seismic waves waves on a string Electromagnetic waves - can travel without a medium examples: light, radio waves, infrared, ultraviolet, x-rays, gamma rays Spring 2011 PHYS 2101 How does the direction of the disturbance relate to the direction of propagation? Transverse waves - direction of disturbance is perpendicular to the direction of propagation examples: sinusoidal waves Longitudinal waves - direction of disturbance is parallel to direction of propagation examples: sound waves http://webphysics.davidson.edu/physlet_resources/bu_semester1/index.html Spring 2011 PHYS 2101 Does the wave appear to move or not? Traveling waves - can observe wave moving in a particular direction Standing waves - wave does not appear to be moving in space http://zonalandeducation.com/mstm/physics/waves/interference/waveInterference2/WaveInterference2.html Spring 2011 PHYS 2101 x ( t ) = A cos( ϖ t + φ ) Displacement at time t Amplitude Phase Angular frequency Time Phase shift Spring 2011 PHYS 2101 ) sin( ) , ( φ ϖ + ± = t kx A t x y Displacement at position x and time t Amplitude Phase Angular frequency Time Phase shift Angular wave number Position Direction + To the left- To the right Spring 2011 PHYS 2101 What is the equation of the wave whose displacement as a function of position at time t = 0 s is shown on the left and whose displacement as a function of time at the position x = 0 m is shown on the right?...
