Waves Flashcards
What is a rhythmic motion that transmits energy from one area to another?
Wave
What is carried along in a wave?
Energy
A wave in which the motion of the wave travels perpendicular to the energy of the wave.
Transverse Wave
A wave in which the motion of the wave travels in a direction parallel to the energy of the wave.
Compressional/Longitudinal Wave
Waves that do not require a medium to travel through.
Electromagnetic Wave
Waves that require a medium to travel through.
Mechanical Wave
The bending of waves as it travels from one medium to another.
Refraction
The spreading of waves around obstacles; pass through a small opening and spread out after they get passed the opening.
Diffraction
The bouncing back of waves off of a surface.
Reflection
When two waves are in phase and causes amplification.
Constructive Interference
When two waves are completely (180 degrees) out of phase and causes cancellation.
Destructive Interference
The area of the wave that is pressed together.
Compression
The area of a wave that is spread out.
Rarefaction
The number of waves produced per second.
Frequency
The height of a crest above the center line.
Amplitude
The material through which a wave travels.
Medium
The distance between the peaks of two crests.
Wavelength
The top of a wave.
Crest
The bottom of a wave.
Trough
What are the 7 different electromagnetic waves?
radiowave, microwaves, infrared rays, visible light, ultraviolet rays, x-rays, and gamma rays
What are the different parts of a transverse wave?
Crest, trough, wavelength, and amplitude
What are the different parts of a longitudinal wave?
Compression and rarefaction
All electromagnetic waves are?
Transverse waves
What are the colors of visible light in order from longest wavelength to shortest wavelength.
Red, orange, yellow, green, blue, indigo, violet
