Waves

Nature of Waves

100

This is what waves transmit.

Energy

200

This type of wave needs a medium to transmit energy.

Mechanical

300

This type of wave does not need a medium to transmit energy.

Electromagnetic

400

This type of wave vibrates particles perpendicular (up and down) relative to its energy travel.

Transverse

500

This type of wave vibrates particles parallel (back and forth) relative to its energy travel.

Longitudinal

Wave Properties

100

This is the highest point and lowest point on a transverse wave. (Draw a model and label )

Crest (high point) and trough (low point)

200

This is where the particles are closer together and farther apart in a longitudinal wave (draw a model and label)

Compression (close together) and rarefaction (far apart) 

300

This is the maximum distance particles vibrate from their rest position.

Amplitude

400

This is the distance between two identical points on a wave.

Wavelength

500

This is the number of waves produced in 1 second.

Frequency

Wave Energy

100

This amplitude transmits more energy. (higher or lower)

Higher Amplitude=More Energy

200

This wavelength transmits less energy. (Longer or shorter)

Longer Wavelength = Less Energy

300

This frequency transmits more energy. (higher or lower)

Higher Frequency = More Energy

400

This pitch of a sound wave transmits more energy. (higher pitch or lower pitch)

Higher Pitch = More Energy

500

This color transmits more energy. (Red or Purple)

Purple transmits more energy

Wave Interactions

100

This wave interaction is described as a wave traveling through a medium.

Transmission

200

This wave interaction is described as wave bouncing off a medium.

Reflection

300

This is when a wave's energy is transferred into a substance. 

Absorption 

400

This wave interaction occurs when a wave travels through different media and causes the wave to bend and travel in a new direction.

Refraction

500

This wave interaction occurs when a wave bends around a barrier or through an opening.

Diffraction

Wave Math and Medium

100

This is the wave speed of a wave with a wavelength of 30 m and a frequency of 20 Hz. 

600 m/s

200

This is a substance that a wave travels through. It can be a solid, a liquid, or a gas.

Medium or Media

300

This is the wavelength of a wave that has a frequency of 125 Hz and a speed of 5000 m/s.

40 m

400

This is the frequency of a wave with a wavelength of 100 m and a wave speed of 2500 m/s. 

25 Hz

500

This is the location of the particles of a medium before a wave get there.
