Ride the Wave

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

• - 6 cm

• 0 cm

• 6 cm

• 3 cm

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?

• A and B

• A and D

• B and C

• B and D

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

• A

• 2A

• 0

• A/2

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?

• A = 0.10 m; B = 0.20 m

• A = 0.20 m; B = 0.10 m

• A = 0.30 m; B = 0.30 m

• A = 0.15 m; B = 0.15 m

The diagram above represents a periodic wave.

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

• A

• B

• C

• D

The diagram above represents wave movement.

Which two points are in phase?

• A and G

• B and F

• C and E

• D and F

Two waves having the same amplitude and frequency are traveling in the same medium. Maximum destructive interference will occur when the phase difference between the waves is

• 0°

• 90°

• 180°

• 270°

The diagram above represents a standing wave produced in a string by a vibrating wave generator.

How many antinodes are shown in this standing wave?

• 6

• 2

• 3

• 4

While playing, two children create a standing wave in a rope, as shown in the diagram above. A third child participates by jumping the rope.

What is the wavelength of this standing wave?

• 2.15 m

• 4.30 m

• 6.45 m

• 8.60 m

wo waves traveling in the same medium and having the same wavelength interfere to create a standing wave. What is the distance between two consecutive nodes on this standing wave?
