Types of Waves
These waves need matter to travel through.
What are mechanical waves?
The top of a wave is called this.
What is a crest?
Sound waves travel through this type of wave.
What is a longitudinal wave?
Light is this type of wave.
What is an electromagnetic wave?
The number of waves passing a point each second.
What is frequency?
These waves can travel through space.
What are electromagnetic waves?
The bottom of a wave is called this.
What is a trough?
Sound cannot travel through this.
What is a vacuum?
Light travels fastest in this place.
What is a vacuum?
This happens when waves bounce back.
What is reflection?
This wave moves side to side.
What is a transverse wave?
The distance between two crests is this.
What is wavelength?
A higher pitch means this is higher.
What is frequency?
The colors of the rainbow make up this.
What is the visible spectrum?
This happens when waves bend passing through materials.
What is refraction?
This wave moves back and forth.
What is a longitudinal wave?
This measures the height of a wave.
What is amplitude?
Louder sounds have greater this.
What is amplitude?
This color has the longest wavelength.
What is red?
When two waves combine, it is called this.
What is interference?
Ocean waves are an example of this type of wave.
What are mechanical waves?
Waves with greater amplitude have more of this.
What is energy?
This unit measures sound loudness.
What is decibels?
This color has the shortest wavelength.
What is violet?
Waves carry this from place to place.
What is energy?
