Understanding Standing Waves

What is the main difference between a standing wave and a traveling wave?

• Traveling waves have fixed maxima and minima.

• Standing waves move continuously through the material.

• Standing waves have maxima and minima that do not move.

• Traveling waves are formed by the superposition of two waves.

How is a standing wave formed?

• By a wave reflecting off a surface.

• By the interference of two traveling waves with the same wavelength and frequency.

• Through the superposition of two traveling waves with different frequencies.

• By a single wave moving in one direction.

What are nodes in a standing wave?

• Points that oscillate the most.

• Points where constructive interference occurs.

• Points that do not move at all.

• Points where the wave reaches its maximum displacement.

What is the correct definition of an anti-node?

• A point where the wave cancels out completely.

• A point where the wave reaches its maximum and minimum displacement.

• A point on the wave that does not move.

• A point where the wave changes direction.

How is the wavelength of a standing wave defined?

• The distance between two nodes.

• The length of one complete wave pattern.

• The distance from the top to the bottom of the wave.

• The distance between two anti-nodes.

What is the period of a standing wave?

• The time it takes for a node to move.

• The time it takes for an anti-node to go from one extreme to the other and back.

• The time it takes for the wave to form.

• The time it takes for the wave to travel a certain distance.

How is the velocity of a standing wave determined?

• By the distance between two nodes.

• By the speed of the wave moving through the material.

• By the wavelength divided by the frequency.

• By the wavelength multiplied by the frequency.

What is the frequency of a standing wave if its period is 4 seconds?

• 4 Hertz

• 1 Hertz

• 2 Hertz

• 0.25 Hertz

If a standing wave has a wavelength of 4 meters and a frequency of 0.25 Hertz, what is its velocity?

• 1 meter per second

• 2 meters per second

• 0.5 meters per second

• 4 meters per second

Why can a standing wave be described as having a velocity?

• Because it has a wavelength and frequency.

• Because it is stationary.

• Because it is formed by a single wave.

• Because it moves from left to right.
