Wave Interaction

What is the superposition of waves?

• when a single wave splits into two different waves at a point
• when two waves combine at the same place at the same time

How do waves superimpose on one another?

• by adding their frequencies
• by adding their wavelengths
• by adding their disturbances
• by adding their speeds

What is interference of waves?

• A superposition of two waves to form a resultant wave with higher or lower frequency.
• A superposition of two waves to form a wave of larger or smaller amplitude.
• A superposition of two waves to form a resultant wave with higher or lower velocity.
• A superposition of two waves to form a resultant wave with longer or shorter wavelength.

True or false? The two types of interference are constructive and destructive interference.

• True
• False

What are standing waves?

• waves that appear to remain in one place and do not seem to move
• waves that seem to move along a trajectory

Standing waves are formed --

• by the superposition of two or more waves moving in opposite directions.
• by the superposition of two or more waves moving in the same direction.
• by the superposition of two or more waves moving in perpendicular directions.
• by the superposition of two or more waves moving in any arbitrary directions.

The reflection of a wave is --

• the change in amplitude of a wave when it bounces off a barrier.
• the change in frequency of a wave when it bounces off a barrier.
• the change in velocity of a wave when it bounces off a barrier.
• the change in direction of a wave when it bounces off a barrier.

Inversion occurs when a wave reflects off --

• a fixed end, and the wave amplitude changes sign.
• a loose end, and the wave amplitude changes sign.
• a fixed end without the wave amplitude changing sign.
• a loose end without the wave amplitude changing sign.

The following is an example of which type of interference? 

• constructive 
• destructive
