What is a wave?

What is a disturbance that carries energy

100
The distance from crest to crest or trough to trough?
What is wavelength
100
The bending of light waves around a barrier?
What is diffraction
100

What is pitch?

a description of how high or low the sound seems to a person

200
Waves that use matter to transfer energy?
What is mechanical waves
200
This color has the longest wavelength and the lowest frequency?
What is red.
200

What is happening to light when you see the color black?

All visible light waves are being absorbed

200
What is volume?

What is how loud or quiet something sounds.

300
A wave who's energy causes the matter in the medium to move up and down at right angles?
What is transverse waves
300
Why do you see lightning before you hear thunder?
What is light travels faster than sound
300
Which behavior of light allows magnifying glasses and contact lenses to bend light?
What is refraction
300

Which wave property affects pitch? Which wave property affects volume?

Pitch- frequency

Volume- amplitude

400
What are electromagnetic waves?
What is a wave that does not require a medium to transfer energy
400
Name 5 tpes of electromagnetic waves.
What is Radio waves, Infared waves, microwaves, Xrays, Gamma rays, ultraviolet waves, visible light waves
400
State the definition for reflection, refraction, diffraction, and absorption. (Key words)
What is bounce back, bends when it goes from one medium t another, bends around a barrier, disappear
400

What is an echo?

a reflective sound wave

500
Name an electromagnetic wave with low energy and then name an electromagnetic wave with high energy?
What is a radio wave has low energy and a gamma rays have high energy
500
What is the amplitude measured from? What does the amplitutde tell us about a sound?
What is crest to rest position or trough to rest position. Amplitude tells us how loud a sound is.
500
What happens when light waves go from one medium to another in refraction?
What is changes speed
500

What is the doppler effect?

The change in frequency of a wave as its source moves in relation to an observer
