Wave Properties
The "tops" of a transverse wave pattern are called this.
What are crests?
The type of wave that gets very large at Mavericks.
What is an ocean wave?
The medium that the sound waves we hear travel through.
What is air?
When light waves bounce off of a substance.
What is reflection?
The numbering system that computers use, which consists of only two digits (0 and 1)
The "bottoms" of a transverse wave pattern are called this.
What are troughs?
The category of wave that needs a medium to travel through.
What is a mechanical wave?
The property of a sound wave that determines the pitch of a sound.
What is frequency?
Darker objects do this more to light waves than brighter objects.
What is absorption?
A fiber optic cable may stop working if this happens
What is bending too much?
This is any unwanted sound or interference that distorts or distracts from a signal
What is noise?
The type of wave we made by pushing the end of a slinky back and forth (not the side-to-side one).
What is a compression wave?
This type of modulation is used for radio stations that play music or need better sound quality.
What is frequency modulation?
A very narrow, focused beam produced by a laser is called this
What is coherent light?
This explains how light travels through a fiber optical cable without exiting the cable
What is total internal reflection?
The wave property symbolized by this greek letter: λ
What is wavelength?
Visible light is a part of this spectrum, as well as all other types of light.
What is the electromagnetic spectrum?
The property of a sound wave that determines the loudness or volume of a sound.
What is amplitude?
List three uses for lasers in everyday life
What are:
Phone
TV
Internet
Bar Codes
Laser Printers
Wireless Mouse
Cutting, welding and engraving
Playing with cats
Name 3 benefits of Digital Waves over analog
Achieve better resolution and sound fidelity
less affected by sources of noise
Can be stored, copied and transmitted more reliably
Use available broadcast frequencies more efficiently
Can provide more sound and video choices such as interactive features and on-demand services.
Do this to make a digital wave become more like an analog wave
What is increase the sampling rate to very high frequencies
When these waves are drawn, they look square and rigid due to their limited sampling size.
What are Digital Waves?
Sports and talk radio stations tend to use this type of modulation
What is amplitude?
When the angle of an incident beam passing through a refractive material is extreme enough that it no longer refracts but reflects back.
What is total internal reflection?
Which image resolution will be more clear and detailed? Why?
256 X 256
or
512 X 512
512 X 512. Increasing the sampling rate of pixels determines the quality of the image
