Wave Facts
100
I am a wave that can travel through a vaccum as well as a medium.
What is an Electromagnetic Wave?
100
This type of wave has the shortest wavelength and the highest frequency.
What is a Gamma Ray?
100
This is what occurs when light bends, such as when viewing a fish in a pond.
What is refraction?
100
The color of an object depends on these two factors.
What is the material of the object and the light that strikes the object?
100
This is what all waves carry.
What is energy?
200
What two things make EM Waves different from one another?
What is frequency and wavelength?
200
This type of ray allows us to cook food and talk on cell phones.
What is a microwave?
200
This is what a material is when it transmits light, allowing nearly all the light that strikes it to pass through.
What is transparent?
200
These are the three primary colors of light.
What is red, blue, and green?
200
This type of wave was discussed before Christmas break and requires a medium for energy to travel through.
What is a mechanical wave?
300
The speed of light in a vacuum (c) in meters per second.
What is 3.00 x 10^8
300
Visible light falls between ________ infrared rays
What are ultraviolet (UV) rays?
300
Your desk is _________ because it does not transmit light and you cannot see through it.
What is opaque?
300
This is the color made when the primary colors of pigment: magenta, cyan, and yellow mix together.
What is black (or dark brown)?
300
This type of wave is ONLY transverse.
What is an electromagnetic wave?
400
These packets of electromagnetic energy sometimes act like a wave and sometimes like a particle. (What are the called)
What is a photon?
400
This is the color with the shortest wavelength in the visible light spectrum.
What is Violet?
400
This is a behavior of light that occurs when light bounces back at a congruent angle and an image is displayed.
What is reflection?
400
In a prism the _____________ wavelengths refract more resulting in the colorful visible light spectrum.
What is shorter?
400
What two types of waves is a radio wave? (Mechanical, Electromagnetic, Sound, Transverse, Longitudinal)
Electromagnetic and transverse
500
This property of light decreases as photons travel farther from the source.
What is intensity?
500
These rays are used in the medical field to kill cancer cells and make pictures of the brain, and in industrial situations as an inspection tool.
What are Gamma Rays?
500
A wave exhibits this behavior when it has to pass through a smaller opening in a barrier.
What is diffraction?
500
This is the process in which white light separates into colors.
What is dispersion?
500
The measure of the height of a wave from resting point to crest is called ______________?
What is amplitude?
