Electromagnetic spectrum
100
Depends on temperature and speed of medium
What is the speed of sound
100
Occurs when light "bounces" off of a surface such as a mirror
What is reflection
100
When two or more waves overlap and combine to form a new wave
What is interference
100
State of matter where particles move fastest
What is gas
100
Range of me waves that you can detect with your eyes
What is visible light
200
Related to frequency of a sound wave
What is pitch
200
The tool that helps you see the electromagnetic spectrum when light waves hit it
What is a prism
200
Occurs when an object causes a wave to change direction and bend towards it.
What is diffraction
200
energy stored in an object that has potential to fall
What is gravitational potential energy?
200
Frequencies higher than visible light (clue:sunburns)
What is ultraviolet
300
radio transmission is communicated in these two ways of modulation
What is Am and Fm
300
Transmits almost all light absorbing and reflecting little
What is transparency
300
Interference in which waves "add" to each other
What is constructive interference
300
Educated guess or testable prediction
What is a hypothesis
300
Ultra-high frequencies that can travel through matter and age cells
What is gamma rays and x-rays
400
Related to amplitude of sound
What is loudness
400
Range of em waves you can detect with your eyes
What is visible light
400
Occurs when waves "subtract" from each other
What is destructive interference
400
Elements that are located on the stair step and have both metallic no non-metallic properties
What are the metalloids
400
type of em wave that is used in sattelites and remote controls.
What is infared waves
500
The medium in which sound waves travel fastest
What are solids
500
the reflection of light from a surface such that an incident ray is reflected at many angles
What is diffuse reflection
500
The angle of incidence of a wave is always equal to the angle of reflection
What is the law of reflection
500
Energy stored in chemical bonds
What is elastic potential energy or chemical energy
500
The number of vibratons per second (Hz)
What is frequency of a Em wave
