beats.iwp

The blue and green waves are superimposed to produce the red wave. When the frequencies are nearly the same, beats are produced. Determine the frequencies of the green and blue waves. Also determine the beat ..

doppler4.iwp

A source of point spherical waves moves along the x-axis at constant velocity. The current position of the source is indicated by a red dot. Note that the spacing of the dark, vertical grid lines ..

doppler5.iwp

A source of point spherical waves moves along the x-axis at constant velocity. The current position of the source is indicated by a red dot. The spacing of the dark, vertical grid lines is 200 m. ..

plucked-cord.iwp

This animation represents waves on a string plucked at its center. The yellow line is the actual waveform that would appear. This can be thought of as the superposition of two waves (blue and red) ..

trav-wave-3.iwp

Consider the following model of a linear medium such as a string: a chain of point masses joined by light, strong threads. Traveling waves of constant frequency and wavelength are generated on the medium. The ..
