Physics
Rotation of a second hand on a clock is
1/60hz
Mechanical waves propagate or move through a medium because
One particle pushes or pulls on the adjacent particle which pushes or pulls on the next particle...
Longitudinal waves travel
Parallel
On a free end the pulse will be
Transmitted
The portion of the pulse that passes into the other medium is referred to as
Transmitted pulse
Amplitude doesn't affect time
True
Crest to medium trough to medium
Amplitude
An open end of a wind instrument creates an, while a closed end creates a
Antidote; node
The positions along the medium that are undergoing rapid motion between a maximum positive and maximum negative displacement are known as, they are opposite of the points of no displacement
Antinodes
Waves add together to create a larger amplitude.
Constructive interference
Wavelength is from
Crest to crest trough to trough
As the wavelength of a wave in a uniform medium increases, its frequency will
Decrease
As frequency of a wave increases, the period of the wave
Decreases
Waves cancel one another out to create an amplitude of zero
Destructive interference
Pulse is a single disturbance, while a wave is a repeated periodic disturbance that moves through a medium.
Difference between a pulse and a wave
Transverse waves that do no need a medium to travel through. They are only waves that we know of that don't need a medium
Electromagnetic waves
Waves are not physical objects they are, thereof waves can occupy the same space at the same time.
Energy traveling through a medium
An ocean wave will transport ocean water from near the middle of the ocean to a location near the shore
False
As a wave moves through a medium, the individual particles of the medium move from source of the wave to another location some distance away.
False
Destructive interference occurs when a trough meets up with another trough at a given location along the medium
False
Two sound waves could never interfere in such a manner as to cancel each other out and produce silence
False
When two pulses meet up with each other while moving through the same medium, they have a tendency to bounce off each other and return back to their origin
False
Work is a, acting over some amount of, to cause a change In
Force; distance; motion
The number of cycles of a periodic wave per unit time is called the waves
Frequency
Each node is separated by the adjacent node by a distance that is equal to
Half wavelength
The speed of a wave refers to
How far a given point on the wave travels per unit of time
A blank is a force acting over some amount of time to cause a change in momentum
Impulse
The superposition of two waves creates
Interference
Fixed end pulse is
Inverted
Units of work
Joule, foot x pound, Nx M, Kg x m2 / sec2
Wavelength is greatest in the
Least dense media
When a wave passes across the boundary from one medium to another medium, the speed is greater in the
Least dense media
The reflected pulse only Becomes inverted only when the incident wave is in the
Less dense medium and headed towards the more dense medium.
Sound waves are
Longitudinal; compressional
Which if the following categories of waves requires a medium in order to transport energy from one location to another
Mechanical
When a force is applied to do work on an object, does the object always accelerate
No
The positions along the medium that appear to be stationary are known as, they are points of no displacement
Nodes
Free end pulse is
Not inverted
The times it takes for one full cycle or for one wavelength to pass a point is called the
Period
Many wave pulses at a specific periodic time intervals
Periodic wave
Transverse waves travel
Perpendicular
Brains interpretation of frequency
Pitch
A portion of the pulse is, and remains in the same medium
Reflected
On a fixed end the pulse will be
Reflected
Work is a, a + or - sign indicates information about
Scalar; whether the work adds or removes energy from the object
Period is
Seconds per vibrations
Periodic waves are reflected and inverted and interfere with one another creating standing waves
Standing waves
As the wavelength of a wave in a uniform medium increases, its speed
Stays the same
The properties of the medium through which the wave travels
The speed of the wave depends on
As a mechanical waves move through a medium, particles of the medium undergo a periodic and repeated vibration about a fixed position
True
Constructive interference occurs when a crest meets up with another crest at a given location along the medium.
True
Destructive interference occurs when a pulse with an amplitude of +t units interferes with a pulse with an amplitude of -5 units
True
Shorter the wavelength higher the frequency
True
Waves are a means of transporting energy from one location to another without actually displacing matter from one location to another
True
Waves are created by a vibriation
True
Frequency is
Vibrations per second
