Wave Properties
Any disturbance that transfers energy from place to place.
Wave
When waves are bent due to traveling through a medium and then into a different medium changing speeds.
Refraction
Sound waves travel faster in materials that are harder to compress. Sound waves travel fastest in solids and slower in gases.
Stiffness
Light is an electromagnetic wave that is shaped as __________ wave.
Transverse
When light hits this type of material, light is scattered thus allowing you to see through it, but the image will be blurred.
Translucent
This type of energy is in the form of visible light, radio waves, Xrays, and microwaves.
Electromagnetic Radiation
Energy of the wave is transferred to the material it interacts with. Example: Solar Panels
Absorption
Amount of energy a sound wave carries per second through a unit area.
Intensity
When a beam of high frequency light shines on some metals, it knocks some tiny particles called ______ out of the metal.
Electrons
The color of a(n) ______object is the light wave that is reflected.
Opaque
The matter a wave moves through is a __________. Mechanical waves cannot move through a __________.
Medium, Vacuum
Waves that are blocked by an obstruction and are not converted to another wave. They change direction though in the opposite direction.
Reflection
If a sound's power level increases from 20 dB to 100 dB by what factor does the power increase? Are sounds harmful to the human ear over 100 dB.
10 to the 8th power.
10x10x10x10x10x10x10x10
What waves in the electromagnetic spectrum can be used to stop the growth and reproduction of cancer cells.
Gamma Radiation
An object is this color if it absorbs all of the color wavelengths.
Black
The distance between the peak of the crest to the resting point.
Amplitude
Waves don't travel in straight lines. They can travel around corners.
Diffraction
This is a factor that can affect the speed of sound waves. In a solid if this increases then the speed of the wave decreases.
Temperature
Which visible light wave/color would you use in a photography dark room and that is because the __________ is the longest.
Red and Wavelength
The surface of this mirror curves inward.
Concave
What are the two parts of a longitudinal wave?
Rarefaction and Compression
When two opposing waves meet and take on the energy of both making crests higher and troughs lower when they meet and then continue with its original energy or cancel each other out are forms of ......
Interference
The amount of matter in a given volume. When a material is higher in ___________, the sound travels slower.
Density
Rank these types of waves from the lowest frequency to the highest frequency:
Xrays; UV Rays; Radio Waves; Microwaves; Infrared Waves
Radio, Micro, Infrared, UV, Xrays
A lens bends light. Sometimes it will show as upside down. This is because lenses _______ light.
