Electromagnetic spectrum
These waves have the shortest wavelength but the most energy.
What are gamma rays?
This is the number of complete cycles in a given time.
What is frequency?
This refers to a wave bouncing off a surface it cannot pass through.
What is reflection?
Electromagnetic waves differ from mechanical waves in that they can travel through this.
What is a vacuum?
This is the material through which a wave travels.
What is a medium?
These waves have the longest wavelength and the lowest amount of energy.
What are radio waves?
The speed of an object can change when it enters a new_______.
What is medium?
When a wave enters a medium at an angle, _______ occurs because one side of the wave moves more slowly than the other side
What is refraction?
An example of an electromagnetic wave is a light wave. Light waves are categorized as this type of wave.
What is a transverse wave?
In these types of waves, rarefaction is the area where the coils are farthest apart.
What are compression or longitudinal waves?
These are the only waves on the electromagnetic spectrum that we can see.
What are visible light waves?
The distance between a point on a wave and the same point on the next cycle of that wave is known as this.
What is wavelength?
A wave _______ more if its wavelength is large compared to the size of an opening or obstacle.
What is diffracts?
This is light that passes through slits in a filter.
What is polarized light?
These are the highest point and lowest point of a transverse wave, respectively.
What are the crest and trough?
These waves can cause sunburn or skin cancer.
What are UV waves?
The more energy a wave has, the greater its ______ is.
What is amplitude?
These are two types of interference.
What are constructive and destructive?
Electromagnetic waves are transverse waves consisting of changing electric fields and changing ________.
What are magnetic fields?
This type of mechanical wave causes the medium to vibrate at right angles to the direction in which the wave travels.
What is a transverse wave?
These waves are used in TV remotes.
What are infrared waves?
If you assume that waves are travelling at a constant speed, then wavelength is _______ _________ to frequency
What is inversely proportional?
This forms only if half a wavelength or a multiple of a half a wavelength fits exactly into the length of a vibrating cord.
What is a standing wave?
While speed of an electromagnetic wave is always the same, these two properties of waves can change.
What are wavelength and frequency?
These waves are the fastest type of longitudinal wave produced by earthquakes.
What are P waves (primary waves)?
