transverse wave direction in which the wave travels
TRANSCRIPT
Transverse Wave A wave that causes a medium to vibrate at right angles to the direction in which the wave travels.
Longitudinal Wave A wave in which the vibration of the medium is parallel to the direction the wave travels.
Surface Wave A wave that travels along a surface separating two media.
Can be any of the three states of matter: A solid, liquid, or gas
Transverse waves Move perpendicular to the source
Longitudinal waves Move in the same direction (parallel) as the source
Frequency The number of complete cycles in a given time.
Period The time required for one cycle, a complete motion that returns to it’s starting point.
Hertz (Hz)
Amplitude
Reflection When a wave bounces off a surface at the same it approaches.
Diffraction The bending of a wave as it moves around an obstacle or passes though a narrow opening.
Refraction Bending of a wave as it enters a new medium.
Constructive interference When waves combine and become larger.
Destructive interference When a wave collides and become smaller
A wave that appears to stay in one place.
Speed = Wavelength x frequency Speed = 50 m x 34.5 hz Speed = 1,725 m/s
Speed = Wavelength x frequency Speed = 23.4m x 100 hz Speed = 2,340 m/s
Wavelength = Speed / frequency Wavelength = 36 m/s / 23 Hz Wavelength = 1.57 m
Apparent shift in pitch due to motion of a sound source
Electromagnetic Wave
Electromagnetic Spectrum
The intensity decreases as you move farther from a source
3 x 108 m/s
ROY G. BIV
Red, Orange, Yellow, Green, Blue, Indigo, Violet
Black
White
A transparent material transmits light, which means it allows the light that strikes it to pass through it.
Translucent material scatters light. You can see through the material, but the objects you see through do not look clear.
Material absorbs or reflects all of the light that strikes it.
Any Questions!!!!
Good Luck and Study !!
