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 the law of reflection?

The angle of reflection is equal to the angle of incidence.

What is the speed of a wave with a wavelength of 5m and a frequency of 105hz?

525 m/s

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 a compression?

A squished together part of a longitudinal wave.

200

What is the wavelength if the speed is 1,000 m/s and the frequency is 4 hz?

250 m

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

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 Newton's Second Law?

force is equal to the mass times acceleration of an object

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.

What are our FOUR definitions for science?

1. Science is a BODY of KNOWLEDGE 

2. Science is a PROCESS OF DISCOVERY (Scientific Method!!!!)

3. Science is a possibly changing theory 

4. Science is a study of what God Created ON PURPOSE FOR A PURPOSE
