Wave Basics
A repeating disturbance that transfers energy from one place to another.
What is a wave?
A wave bounces back after hitting a surface.
What is reflection?
A sound wave is this type of wave.
What is a mechanical wave?
This happens when light bounces of a mirror.
What is reflection?
A message or information sent from one place to another.
What is a signal?
The maximum distance a wave moves from its resting position.
What is amplitude?
A wave passes through a material.
What is Transmission?
A mechanical wave needs this in order to travel.
What is a medium?
This happens when a dark shirt takes in light energy.
What is absorption?
To convert information into digital form.
What is digitize?
The distance from one point on a wave to the same point on the next wave.
What is wavelength?
A material takes in the energy of a wave.
What is Absorption?
These are known as a medium through which a sound wave can travel.
What is air, water, solid?
This happens when light passes through a clear window.
What is transmission?
This signal changes continuously.
What is analog?
Tells how many waves pass a point in a certain amount of time.
What is Frequency?
Light bends or changes direction as it moves between different materials.
What is refraction?
True or False.
Sound can travel through empty space.
What is false?
This is a transparent object that can bend or change the path of light.
What is a lens?
This signal uses separate values, usually represented as 0s and 1s.
What is digital?
The amplitude of a wave increases, generally the amount of energy carried by the wave _____________.
What is increases?
A student sees a straw appear bent when it is placed in a glass of water.
What is refraciton?
Light does not need a medium and is known as this kind of wave.
What is electromagnetic?
A transparent object that can separate visible light into different colors.
What is a prism?
Unwanted information or interference that can affect a signal.
What is noise?
