The diagram above represents two identical pulses approaching each other in a uniform medium.

As the pulses meet and are superposed, the maximum displacement of the medium is

Two speakers, S₁ and S₂, operating in phase in the same medium produce the circular wave patterns shown in the diagram above

At which two points is constructive interference occurring?

The diagram above shows two pulses of equal amplitude, A, approaching point P along a uniform string.

When the two pulses meet at P, the vertical displacement of the string at P will be

The diagram above shows two pulses approaching each other from opposite directions in the same medium. Pulse A has an amplitude of 0.20 meter and pulse B has an amplitude of 0.10 meter.

After the pulses have passed through each other, what will be the amplitude of each of the two pulses?

The diagram above represents a periodic wave.

Which point on the wave is 90° out of phase with point P?
