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
