Waves Flashcards
Medium
A medium is any substance that a wave moves through
Mechanical Waves
Waves that transfer through matter are known as Mechanical Waves
Transverse Wave
In a transverse wave, the direction in which the wave travels is perpendicular, or or at right angles to the direction of the disturbance.
Longitudinal wave
In a longitudinal wave, the wave travels in the same direction as the disturbance
Crest
A crest is the highest point, or peak of a wave.
Trough
A trough is the lowest point, or valley, of a wave.
Amplitude
Amplitude For a transverse wave is the distance between a line through the middle of a wave and a crest or trough.
Wavelength
The distance from one crest to the very next crest is called the wavelength
Frequency
The number of waves passing a fixed point In a certain amount of time is called the frequency
Reflection
The bouncing back of a wave after it strikes a barrier is called a reflection
Refraction
When a wave enters a new medium at an angle, it bends, or retracts
Diffraction
Diffraction is the spreading out of waves through an opening or around the edge of an obstacle
Interference
It is the meeting and combining of waves.
Wave
A wave is a disturbance that transfers energy from one place to another
Radiation
Energy that moves in the form of EM is called radiation
Electromagnetic spectrum
The range of all EM frequencies is known as the electromagnetic spectrum or EM spectrum
Radio waves
Radio waves are EM waves that have the longest wavelengths, the lowest frequencies, and I he lowest energies π±
Microwaves π
Microwaves are EM waves with shorter wavelengths πΈ higher frequencies π and higher energy costs than other radio waves π
Visible light βοΈ
Visible light is the part of the EM spectrum that human eyes can see π
Ultraviolet light β οΈ
The ultraviolet light is the part EM spectrum consists of frequencies above those visible light and partially below those of x-rays π
X-rays
The part of the electromagnetic spectrum that consists of waves with high frequencies and high energies
Gamma rays
Part of the electromagnetic spectrum that consists of waves with the highest frequencies
Infrared light
The infrared light part of the spectrum consists of EM frequencies between microwaves and visible light
Fluorescence π
Occurs when a material absorbs EM radiation of one wavelength and gives off EM radiation of another π
Transmission
Transmission is the passage of an EM wave through a medium π
Absorption is the disappearance of an EM wave into the medium π
Absorption π€
Scattering
It is the spreading out of light rays in all directions
Polarization
Is a quality of light in which all of its waves vibrate in the same direction
Prism
It is a tool that uses refraction to spread out the bends of the wave lengths more than others
Primary colors π¨
These three colors of light which can be mixed to produce all possible colors are β¦β¦ β¦β¦β¦
Primary pigments
The β¦β¦β¦β¦β¦. Are cyanπ yellowπ and magenta π
