6.P.1.1 and 6.P.1.2 Waves, Light and Sound

Forces and Motion Waves 6.P.1.1 Compare the properties of waves to the wavelike property of energy in earthquakes, light and sound. 6.P.1.2 Explain the relationship among visible light, the electromagnetic spectrum, and sight. 6.P.1.3 Explain the relationship among the rate of vibration, the medium through which vibrations travel, sound and hearing. Heat Transfer 6.P.3.1 Illustrate the transfer of heat energy from warmer objects to cooler ones using examples of conduction, radiation and convect…

waves
moving ridges or swells in a body of water (or other medium) that transfer energy in the direction of their motion
medium
Material through which a wave travels
transverse wave
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels. Light Waves
longitudinal wave
A wave in which the vibration of the medium is parallel to the direction the wave travels. Sound waves and P waves.
energy
Is the ability to do work
matter
Anything that has mass and takes up space
wavelength
the distance between the crest of one wave and the crest of the next wave
trough
Lowest point of a wave
crest
Highest point of a wave
amplitude
Height of a wave
frequency
How many waves can pass a given point per second, measured in Hertz (Hz)
reflection
the light energy that bounces off objects
refraction
The bending of a wave as it moves from one medium to another
earthquakes
A sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action
light
Electromagnetic radiation that can be seen with your eyes.
electromagnetic spectrum
Includes all forms of electromagnetic radiation; the types of radiation differ in their frequencies and wavelengths
color
The part of the electromagnetic spectrum that is called visible light and is created by reflected light in your eyes.
vibration
A repeated back and forth or up and down motion
transparent
(adj.) allowing light to pass through; easily recognized or understood; easily seen through or detected
electromagnetic waves
A form of energy that can move through the vacuum of space this includes visible light.
visible light
Electromagnetic radiation that can be seen with the unaided eye and makes up the smallest part of the EMS.
Shortest wavelength of color of visible light
violet
longest wavelength of color of visible light
red
White light
a combination of all colors of visible light on the electromagnetic spectrum
Compression
The part of a longitudinal wave where the particles of the medium are close together.
Rarefaction
a part in a longitudinal wave where the particles are spread apart
mechanical wave
A wave that requires a medium through which to travel
