Wave Behavior
This wave behavior causes a wave to bounce off a surface.
What is reflection?
This part of a wave measures its height from rest position.
What is amplitude?
What is another name for this signal that uses only two values, usually 0s and 1s.
What is binary?
Analog signals are made up of _________________ streaming data.
What is continuously?
This type of wave does not need a medium to travel.
What is electromagnetic wave?
This wave behavior happens when a wave slows down and bends as it enters a new medium.
What is refraction?
This wave property is the distance between two crests or two troughs.
What is wavelength?
Digital signals usually travel as in a system in this form.
What is wave pulses?
Give an example of an analog device.
What is a record player, analog clock, AM/FM radio.
An echo is an example of this wave property.
What is reflection?
This wave behavior occurs when wave energy is taken in by a material.
What is absorption?
This wave property tells how many waves pass a point in one second.
What is frequency?
This type of signal is used by computers, texting, and the internet.
What is digital signals?
Give one disadvantage of analog signals compared to digital signals.
What is signal quality decreases with distance/noise or affected by interference?
Mechanical waves travel fastest through this state of matter?
What is a solid?
This wave behavior allows waves to pass through a material.
What is transmission?
This wave property is affected when frequency increases or decreases.
What is wavelength?
Give an example of a digital device.
What is a cellphone, computer, digital tv.
This type of signal has greater resolution.
What is an analog signal?
Electromagnetic waves travel fastest through this medium.
What is air?
This wave behavior explains why sound is quieter after passing through a wall.
What is absorption?
This wave part is directly related to the energy carried by a wave.
What is amplitude?
People prefer digital televisions over analog because digital TV is more _________________.
What is reliable or higher quality?
AM stands for this type of radio signal.
What is amplitude modulation?
This wave property causes rainbows.
What is refraction?
