Waves

Wave Parts

100

The peak of a wave

Crest

200

The height of a wave

Amplitude

300

30 full waves pass by a fixed point every second. The frequency, in Hz, is...

30 Hz

400

The number of wavelengths I complete if my wave starts from the middle, goes up, and then goes down back to the middle.

1/2 OR 0.5

500

Another name for a compression wave.

Longitudinal

Sound Waves

100

Changing the amplitude changes this about the sound you hear.

Volume

200

A higher frequency results in a _____________ sounding pitch (higher/lower).

Higher

300

In order to get a lower pitch, I need to ______________ the wavelength (increase/decrease).

Increase

400

By increasing the frequency, I am also _________________ the wavelength (increasing/decreasing)

Decreasing

500

The number of Hz for a concert pitch musical note of A

440 (OR 27.5, 55, 110, 220, 880, 1760, 3520, 7040, etc)

Light Waves

100

The brightness or intensity of light can be increased by increasing this part of a light wave.

Amplitude

200

Radio waves have a really _____________ wavelength (long/short)

Long

300

This small section of the electromagnetic spectrum (from 380 nm to 780 nm) is the only type of light we can see.

Visible

Visible Light

Visible Spectrum

400

Shorter wavelengths of light have _________ energy (high/low).

High

500

The three primary colors according to the subtractive color model/pigment model (absorbing light).

Magenta, cyan, yellow

Instruments

100

Mr. Logan's wife plays this 6 foot 4 inch tall instrument

Harp

200

Prior to the invention of this percussion instrument, similar instruments could only be played at one dynamic (volume).

Piano

300

This instrument is considered the bridge between woodwinds and brass since it is made of brass but uses a reed.

Saxophone

400

Rank the sizes of these three string instruments, starting with the smallest: Cello, violin, viola, double bass.

Violin, viola, cello, double bass

500

This instrument is played without touching it (not once!)

Theremin

Fun with Waves

100

True or False: waves transport matter across distances.

False (they transfer energy)

200

The inventor of the fire tube we used in class.

Ruben

Heinrich Ruben

300

This sound wave was originally thought to have originated from a giant sea monster in the Pacific and was so loud it was picked up from hydrophones over 2000 miles apart. That would be like a microphone picking up the same sound in Lindon and Miami.

The Bloop

400

The name of the dog that tragically died in the Tacoma Narrows Bridge collapse of 1940.

Tubby

500

Examples of waves include radio waves, microwaves, sound waves, light waves, x-rays, earthquakes, and this fundamental force of the universe that was first detected as a wave in 2015.
