Waves Properties
A disturbance or vibration of a medium that moves through the medium
Wave
The colors of the rainbow that make up the visible spectrum.
Red, Orange, Yellow, Green, Blue, Indigo, Violet.
Red has the longest wavelength & Violet has the shortest.
ROY G BIV
Vibrations that travel through air or another medium and can be heard when they reach a person’s or animal’s ear
Sound
(also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other.
Thermal Energy
It is the highest point of a wave
Crest
Rapid back and forth movements
Vibration
The complete range of frequencies of electromagnetic waves from the lowest to the highest, including, in order : radio, infrared, visible light, ultraviolet, X-ray, and gamma ray waves
Electromagnetic Spectrum
Your perception of the energy of the sound
Volume (loudness)
A measure of the average kinetic energy of the molecules in a substance
Temperature
It is the lowest point on a wave.
Trough
Materials (series of interconnected particles) through which a wave travels
Medium
When light waves bend. Light waves are refracted as they pass through water.
Refraction
The perceived frequency of sound
Pitch
The energy of motion
Kinetic Energy
The part of a longitudinal wave that is more spread out; a decrease in density and pressure in a medium, such as air, especially when caused by the passage of a wave
Rarefaction
Ability to cause changes in matter
Energy
Wave energy we can see, portion of electromagnetic spectrum that is visible to the human eye; made of colors
Visible Spectrum
A pair of flaps on either side of the larynx that are responsible for the production of sound including speech
Vocal Cords
Convection, Conduction, and Radiation are examples of...
Heat Transfer
The densest part of a longitudinal wave; force that tends to shorten or squeeze something, decreasing its volume.
Compression
The number of waves that pass a fixed point in a given amount of time; measured in hertz (Hz)
To get the answer right you need all three terms!
An object that does not allow light waves to pass through it – you CANNOT see through it
An object that allows a few light waves to pass through. You can almost see through these objects.
An object that allows light waves to pass through. You can see through these objects
Opaque, Translucent, Transparent
Which part of the ear has the smallest bones in the body: the hammer, anvil and stirrup?
Middle ear
A substance that does NOT transfer energy easily, or transfers is very slowly.
Insulator
The maximum distance the particles of a medium move from their resting position
Amplitude
