Questions From Reading Activity?

Objectives State the meaning of the term wave intensity. Know the relationship between intensity and energy, time, area, amplitude, and radius. Understand how intensity and amplitude vary with distance from a source that emits wave pulses spherically and for one- dimensional waves.

Introductory Video

Wave Propagation When we study the characteristics of waves, we tend to think of them one-dimensionally Rays instead of wavefronts

Wave Propagation Most waves actually are propagated in multiple directions simultaneously Pebble in a pond Sound waves Light waves

Wave Propagation Wave propagation is all about propagation of energy As waves spread out, the energy also spreads out Same energy over a larger area means a drop in intensity

Wave Propagation For particles exhibitying SHM, Energy is a function of amplitude so, The energy transported by a wave is proportional to the square of the amplitude

Wave Propagation Intensity – The power (energy per unit time) transported across a unit area perpendicular to the direction of energy flow.

Wave Propagation Spherical Wave – A wave that spreads out symmetrically in all directions from its source.

Wave Propagation

Wave Propagation – One-Dimension What’s different for a one- dimensional wave like along a solid bar or within a tube?

Wave Propagation – One-Dimension What’s different for a one- dimensional wave like along a solid bar or on a string? Area remains constant Amplitude remains constant so, Intensity remains constant

Wave Propagation – Real Life What’s different in real life?

Wave Propagation – Real Life What’s different in real life? Frictional damping Amplitude, energy and intensity DO decrease in one dimensional waves Intensity decreases more than the equations predict for spherical waves

Wave Intensity Total energy of a wave is the sum of the energies of the individual particle in movement at any given time

Wave Intensity Total energy of a wave is the sum of the energies of the individual particle in movement at any given time S l = vt

Wave Intensity Total energy of a wave is the sum of the energies of the individual particle in movement at any given time S l = vt

Wave Intensity Total energy of a wave is the sum of the energies of the individual particle in movement at any given time S l = vt

Wave Intensity Total energy of a wave is the sum of the energies of the individual particle in movement at any given time S l = vt

Objectives State the meaning of the term wave intensity. Know the relationship between intensity and energy, time, area, amplitude, and radius. Understand how intensity and amplitude vary with distance from a source that emits wave pulses spherically and for one- dimensional waves.
