Types of Waves
This type of wave needs a medium to travel through.
What is mechanical wave
Light, X-rays, ultraviolet, infrared, and radio waves are all part of this.
What is electromagnetic spectrum?
This is the speed at which a wave is moving
What is wave velocity?
This is where the particles of a longitudinal wave are crowded together
What is compression
When a wave encounters a barrier and it's direction is changed, we say the wave has done this.
What is reflection
This type of wave does NOT need a medium to travel through.
What is Electromagnetic Wave
this is any substance through which a wave can travel
What is a medium
This is The distance from crest to crest, or from trough to trough
What is wavelength?
this is where the particles of a longitudinal wave are spread apart
What is rarefaction
Signal that can be represented as a sequence of discrete values
What is Digital?
Any disturbance that transmits energy through matter or empty space
What is a wave
This is the highest point of a transverse wave
What is a crest
This is the number of waves produced in a certain amount of time
What is frequency?
These are the two main types of waves
What is transverse and longitudinal
Signal that properties change continuously in a given range
What is Analog
This is a waves where the particles vibrate parallel to the direction of the wave
What is longitudinal wave
This is the lowest point of a transverse wave
What is a trough
The distance particles of a wave vibrate from resting position
What is amplitude?
The bending of a wave as the wave passes between two substances.
What is refraction?
Changing the frequency or amplitude of a wave to send a signal.
What is modulate?
This is a wave where the particles vibrate perpendicular to the direction of the wave
What is a transverse wave
Unwanted change or interference with a signal.
What is noise?
If you increase the wavelength, what happens to the frequency?
What is it decreases?
Process by which a substance converts light wave energy into heat.
What is absorption?
This is the word we use to measure frequency
What is hertz
