Wave interference that results in lesser wave amplitude is call ___________ interference

destructive

When the trough of one wave meets the crests of another,n ____________ interference will occur

destructive

If the trough of a wave with an amplitude measuring -4 m collides with the crests of another wave measuring 1 m, what type of interference is this and what is the amplitude of the resulting wave?

destructive interference, -3m

true of false: only sound waves can be reflected

false

true or false: destructive interference occurs when the crests of two waves overlaps

false

T or R: Refraction occurs because waves change speed in a new medium

true

Wave interference refers to wave interactions that can occur between a wave and ______

two of the above

Types of wave interactions include

all of the above

An echo is an example of the type of wave interaction called

reflection

When two waves pass through each other to opposite directions, the interference affects their______

Amplitude

Diffraction

Bending of a wave around an obstacle

When the crests of one wave the crests of another, ________ interference will occur

Constructive

If the crests of a wave will an amplitude measuring 3 m collides with the crests of another wave measuring 2 m, what type of interference is this and what is the amplitude of the resulting wave?

Constructive interference, 5m

Wave interactions refer to interactive between a wave and

Its medium

why do standing wave occur?

Waves may reflect off an obstacle that they are unable to pass through.

When the trough of one wave meets of another,__________ interference will occur

constructive

Wave interference that results is greater wave amplitude is called _________________ interference
