Interference

When waves combine in phase and create a larger amplitude they create________interference

Constructive Interference

When waves superpose to form a smaller wave

Destructive Interference

A wave that oscillates in a fixed location is a

Standing Wave

Points on a standing wave that do not move

Nodes

Which graph shows the wave with the greatest amplitude?

A. Shows the wave with the greatest amplitude

Which of the above waves has the longest wavelength?

Wave # 3

In __________ waves, matter in the medium moves forward and backward in the same direction the wave travels.

Compressional or longitudinal Waves

__________ is a repeating disturbance that transfers energy through matter or open space.

Wave

A wave in which particles propagate at right angles to the direction the wave travels.

Transverse Wave

Sound reaches our ears because sound makes air particles

vibrate

Sound is a type of mechanical energy that is transmitted in the form of

Longitudinal waves

Through which medium will sound travel the fastest?

Solid

Sound waves are classified as _________ waves

Compressional or longitudinal Waves

These are the parts of a longitudinal wave

Compressions or expansions/rarefactions

The frequency of the corresponding sound wave

Pitch

Sounds with a frequency less than 20 Hz

Infrasonic

Result of two waves interfering with one another to create loud and soft sounds

Beats

The amount of sound energy passing a given area in a given time

Intensity

The person in front of this car hears a sound that is _________

Higher in frequency

When you double the loudness of a sound, you increase the decibel by

10 dB.

It takes ____ anti nodes to make a wavelength

two

__________ is the distance from the top of one crest of a transverse wave to the top of the next crest in that wave.

Wavelength

Standing waves require a _____ at the bottom and a _____at the top

Node, antinode

Wavelength and frequency are related this way

Inversely

Final Jeopardy Draw the two types of waves and include labels of their characteristics
