2

As a transverse wave travels through a rope from left to right, the parts of the rope _____.

move along a sine-wave like path from left to right

oscillate back and forth about a fixed location

move along a line from left to right

2

The frequency of a wave describes _____.

how far particles move away from their normal resting position

how fast a point on the wave moves along the medium

how often particles of the medium oscillate back and forth

4

The wavelength of a wave increases if the ______.

4

A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound

vibrates longitudinally; the longitudinal movement of air produces pressure fluctuations.

is like all waves; it is able to bend into the regions of space behind obstacles.

is able to reflect off fixed ends and interfere with incident waves

waves have a speed that is dependent only upon the properties of the medium.

is more dense than air and thus has more inertia, causing the bunching up of sound.

4

A sound wave is different than a light wave in that a sound wave is

produced by an oscillating object and a light wave is not.

capable of existing with a variety of frequencies and a light wave has a single frequency.

not capable of diffracting and a light wave is.

not capable of traveling through a vacuum.

2

Which of these has a 'Higher' frequency?

2

Which of these has a 'Higher' period?

4

Two musical notes that have a frequency ratio of 2:1 are said to be separated by an octave. A musical note that is separated by an octave from middle C (256 Hz) has a frequency of _____.

10

Drag and drop each of the following items to the correct category.

two downward pulses traveling in the same direction within a medium
an upward and downward pulse traveling in opposite directions within a medium
an upward and downward pulse traveling in the same direction within a medium
considered 'nodal'
two upward pulses traveling in opposite directions within a medium
considered 'anti-nodal'

Constructive Interference
Destructive Interference
Neither

Sound is not a transverse wave, but it can still interfere because...

...the pitch of two waves will always be percevied to be quiet and loud in different areas.

...we can measure it with a loudspeaker, convert it into electromagnetic representations of compressions and rarefactions, and see them interfereing with it ourselves.

...the change in pressure of the particles is converted into waves so that we can see them, and they interfere because that's how our interpretation of transverse waves works.

...when two or more sound waves occupy the same space, their pressures affect one another. The waves do not bounce off of each, but they move through each other.

2

The frequency or frequencies at which an object tends to vibrate with when hit, struck, plucked, strummed or somehow disturbed.

4

A harmonic ...

is created at any frequency within an object

has a pattern of nodal and anti-nodal meeting at the same spots in the standing wave

is created at specific frequencies within an object

can be represented as a standing wave

2

What seperates noise from music?

whether or not there was a forced vibration

there is no seperation; everything can be and have musical qualities

a mathematical relationship between frequencies produced by the obect

it's a generational thing, in that anyone older than you always thinks your music is noise

Pictured here is the formula we used in our resonance lab with the PVC pipes:
Explain each part of the formula, and why it was needed.

4

A blue light wave approaches a mirror at 30degrees, which means that the light wave will reflect off the mirror at _____ degrees.

4

Describe light Diffraction.

8

What did the Double Slit Experiment demonstrate about electrons?

2

Where could you find all of the visible light in the EM Spectrum?

4

Where is the longest wavelength in this spectrum?
