What are waves?
Rhythmic disturbances that carry energy without carrying matter.
100
What is a crest?
the highest part of a transverse wave
100
What is a reflection?
The bouncing back of an object or a wave when it hits a surface through which it cannot pass
100
What is loudness?
your perception of the energy of a sound
100

How is the EM Spectrum divided into groups?


by wavelength or frequency

200
What are mechanical waves?
The type of waves that use matter to transfer energy.
200
What is a wavelength?
the distance between crest to crest or trough to trough in a transverse wave or from compression to compression or rarefaction to rarefaction in a compressional wave.
200
What is refraction?
the bending of waves due to a change in speed
200

What is Hertz?

unit for measuring frequency of a wave

200

What is visible light?

the region of the EM spectrum that can be seen by humans

300
What is a rarefaction?
The parts where the coils or particles are spread out in a longitudinal or compressional wave
300
What is frequency?
the number of complete waves that pass a given point in a certain amount of time
300
What is diffraction.
The bending of waves as they move around a barrier or pass through an opening
300
What is pitch?
a description of how high or low the sound seems to a person
300
what type of wave is light?

transverse, electromagnetic

400
What is a medium?
The material through which a wave travels
400

What is compression?

the area of a longitudinal wave where particles are closest together (more dense)

400
What is constructive interference?
The interference that occurs when waves combine to make a wave with a larger amplitude
400
What is an echo?
a reflective sound wave
400

What has higher energy, microwaves or Xrays? Bonus 100 points...if you can explain.

Xrays.  They have a shorter wavelength and higher frequency. High frequency = high energy

500
What are types of electromagnetic waves?
Possible answers: Radio waves Infrared waves Visible light waves Ultra violet waves X-Rays Gamma Rays
500
What is Amplitude?
a word used to describe that amount of energy a wave carries.
500
what is destructive interference?
this type of interference can reduce noise.
500
What is the doppler effect?
The change in frequency of a wave as its source moves in relation to an observer
500

What is a Gamma Ray?

the highest energy waves on the EM Spectrum (highest frequency, shortest wavelength)
