What are waves?

disturbances that carry energy

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
What is music?
a set of notes that combine in patterns that are pleasing
200

What are mechanical waves?

The type of waves that use a medium

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 

200

What happens to sound when there is more energy present

it gets louder

200

What is resonance?

this occurs when an object is made to vibrate 

300

What is a rarefaction?

The parts where the coils or particles are spread out in a longitudinal 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 electromagnetic wave has the highest frequency?

Gamma Ray

400
What is a medium?
The material through which a wave travels
400
What is Hertz?
the unit of measurement for frequency
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 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

Which part of the electromagnetic spectrum can we see?

Visible Light
