Light Waves
This behavior occurs when light bounces off a surface, like a mirror.
Reflection
Unlike light, sound is a mechanical wave, meaning it requires this to travel through.
This type of signal is continuous and changes smoothly over time, like a traditional clock or a vinyl record.
Analog
This is the bending of light as it passes from one medium to another (like air to water), causing it to change speed.
Refraction
Sound waves are this type of wave, where the particles move back and forth in the same direction as the wave.
This type of signal uses discrete "on" and "off" pulses (1s and 0s) to represent information.
Digital
Light is this type of wave, meaning its vibrations are perpendicular to the direction the wave travels.
Transverse
Sound travels fastest through what state of matter?
Solid
This is the main reason digital signals are considered more reliable; they are less affected by "interference" or "________".
Noise
This term describes a material that allows some light to pass through but scatters it, so objects on the other side are blurry.
Transluscent
Frequency of a sound wave is closely tied to this aspect of sound.
Pitch
This is the specific "code" or system of 1s and 0s that computers use to process digital information.
Binary
What makes colors?
An object absorbing all colors except for the one you see, which is reflected
Amplitude of a sound wave is closely tied to this aspect of sound.
Volume
How is sound (like a longitudinal wave) turned into code in something like a phone/computer?
It is digitized into a series of 1s and 0s
