Wave Properties Part 1
What is the highest point in a transverse wave called?
Crest/Peak
What do waves transfer/move?
Energy
What does frequency measure?
How many waves occur in a set time frame
How many types of light are present in the Electromagnetic Spectrum?
Seven
Are Electromagnetic waves transverse or longitudinal waves?
Transverse
What is the lowest point in a transverse wave called?
Trough
What is a wave?
A disturbance that transfers energy from one place to another.
What unit of measurement do we use to calculate frequency?
Hertz
Which is the only type of light in the Electromagnetic Spectrum that humans can see with their own eyes unaided?
Visible Light
Electromagnetic waves are the only type of waves that can travel through _________?
Vacuum/Empty Space
What is wavelength?
The distance between two crests in a transverse wave.
What is a longitudinal wave?
A waves that moves back and forth and the particles move parallel to the wave.
What is a medium?
Any matter a wave passes through.
Which type of light has the least energy/longest wavelength?
Radio Waves
List the order of the speed of an electromagnetic wave based on what it is traveling through from fastest to slowest.
Vacuum, Gas, Liquid, Solid
What is Amplitude?
The height of the wave from the middle to the crest.
What is a compression?
The point in a longitudinal wave where the particles are closest together
The greater the amplitude, the greater the ________ of a wave.
Energy
Which type of light has the most energy/shortest wavelength?
Gamma Rays
Which color of light has the longest wavelength (least energy) and which color of light has the shortest wavelength (most energy)?
1. Red 2. Violet
What is a transverse wave?
A wave that moves up and down perpendicularly to its source.
What is a rarefaction?
The point in a longitudinal wave where the particles are farthest apart.
What is a mechanical wave?
A wave that requires a medium to travel from one point to another.
Which type of light is invisible to the human eye but humans can sense in the form of heat?
Infrared Light
List the order of types of light in the electromagnetic spectrum from longest wavelength (least energy) to shortest wavelength (most energy)
Radio; Microwave; Infrared; Visible Light; Ultraviolet Light; X-Rays; Gamma Rays
