Definition
What is electromagnetic wave?
Electromagnetic waves are transverse waves that travel through empty space.
Have the longest ____________ and the lowest ____________ of all electromagetic waves.
wealength, frequency
What does infrared mean?
Below red
___________ are the electromagnetic waves we can see
Visible Light Rays
What are Gamma Rays?
Shortest wavelength and highest frequency on electromagnetic spectrum
What are mechanical waves?
Mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
The height of a crest or depth of a trough is what?
Amplitude
All waves carry _______ from one place to another.
Energy
A disturbance that carries energy from place to place
Wave
What is lowest part of a transverse wave?
Trough
What is a Wave?
Disturbances that transfer energy without carrying matter.
What is a crest?
the highest part of a transverse wave
What is a reflection and how can it be used to tell the depth of a lake
The bouncing back of a wave when it hits a surface through which it cannot pass. The longer it takes to bounce back, the further away the object is.
What looses energy to the medium quicker, high or low frequency?
What is high frequency
What happens to wave length a wave frequency increases?
What is, gets shorter.
What is medium?
A substance that makes possible the transfer of energy from one location to another, especially through waves.
What is ultraviolet light?
A form of radiation which is not visible to the human eye.
What is destructive interference?
Occurs when two or more waves combine to produce a wave with a smaller displacement.
What is wavelength and frequency?
While speed of an electromagnetic wave is always the same, these two properties of waves can change.
What is visible light?
Makes up a small portion of our electromagnetic spectrum and is the only electromagnetic wave type that we can see.
What is vacuum?
Space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there.
