Pg. 52
As frequency increases what happens? The waves become closer toWaves Ind. 2 & 4 Pass Questions
Pg. 51
What is the amplitude of a transverse wave? Is the distance from the midpoint of the wave to crest or though
What is the midpoint? Is a line through the middle of a wave
What does the amplitude of a wave depend on? Depends on the force that causes the wave
A ______greater ______ force produces a wave with _____more ______ energy and a _ higher _ amplitude.
In mechanical waves what does amplitude measure? How far particles of the medium are moved from their resting positions
In a transverse wave, you can think of amplitude as the what? As the height of a wave
The higher the wave, the ____greater _____ its amplitude.
For sound waves, a greater amplitude means what? Louder sound
gether and carry more energy
As frequency decreases what happens? The waves became more spread out and carry less energy
Draw the low energy and high energy waves on the bottom of the page. Make sure you label them.
Pg. 53
What does wave speed depend on? on the medium through which the wave is traveling
What substance (medium) can sound travel the fastest? A sound wave travels faster through iron than through air
What substance does sound travel the slowest? Air
When a wave moves from one medium to another, what happens to its speed? It changes
All electromagnetic waves travel at the same what in empty space? Through empty space
All electromagnetic waves are said to travel at? The speed of light
Pg. 60
When waves reach the same place at the same time, they what? They interfere with each other
What is that process called? Interference
What is constructive interference? It occurs when two identical parts of waves interfere to produce a wave with greater amplitude
What happens if the crest of one wave interferes with the crest of another wave? The resulting wave has a greater amplitude than either wave
Draw the constructive interference diagram.
The same happens if the _____troughs ______ of two waves interfere.
For longitudinal waves, constructive interference occurs when what two things interfere? Compressions or rarefactions
What is destructive interference? Occurs when two different parts of waves interfere to produce a wave with lower amplitude
The crest of one wave will interfere with the trough of another wave to produce what? A wave with lower amplitude
Draw the destructive interference diagram.
What does interference of sounds waves affect? What you hear
For light waves, a grater amplitude means what? Brighter light
