Term	Definition
Waves	Waves are Oscillations that carry energy.
Oscillation	an up and down or back or forth motion.
Mechanical Energy	Waves that move through vacuums.
Types of Mechanical Waves	Three types of mechanical waves are transverse waves, longitudinal waves and surface waves.
Electromagnetic Waves	one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays
Types of Electromagnetic Waves	the 4 types of electromagnetic waves are X-ray waves Radio waves Television waves Light waves
Wave Properties	are elements we can measure for ANY wave.
Amplitude	is one half the distance between a waves high point.
Crest	low point
Trough	low point
Resting Point	the position of the pointer with respect to the pointer scale when the beam has ceased moving
Wavelength and symbol	is measured from a point on one wave to the same point on the next wave like crest to crest or trough to trough.
Wavelength Units	the distance between two successive crests of a wave.
3 ways to measure	Inches, feet, centimeters
Frequency	the number of waves that pass a fixed point in a given unit if time.
Units for Frequency	hertz
Wave Speed	represented in equations as v (velocity).
Wave Speed Units	the time it takes wave to move from one point to another.
Wave Speed Equation	wave speed = frequency * wavelength (abbreviated as v = f * ).
Medium	an agency or means of doing something.
Reflection	is when a wave bounces off a surface.
Law of Reflection	explains that waves get reflected in a particular way - a wave reflects at the same angle as the angle that it moved toward the barrier.
Reflected Ray	A ray of light or other form of radiant energy which is thrown back from a non permeable or non absorbing surface; the ray which strikes the surface before reflection is the incident ray.
Incident Ray	is a ray of light that strikes a surface.
Refraction	and is caused by waves traveling at different speeds in different mediums ( or substances ).
Diffraction	is bending of waves around a barrier or the or spreading of waves past small openings.
Interference	The result of waves colliding with each other.
Constructive Interference	or they interfere with each other and cancel each other out.
Destructive Interference	When you jump on a trampoline with friends. you experience constructive and destructive interference.
Absorption	is the transfer of energy from a wave to matter as the wave passes through it.
Absorbed Colors	absorb only specific wavelengths which is how we see color.
Reflected Colors	When we see a red apple, it's because every other color EXCEPT red is being absorbed and red is being reflected.
Electromagnetic Spectrum	Electromagnetic waves are TRANVERSE WAVES, made of electric and magnetic fields.
Visible Light Spectrum	The only kind of electromagnetic wave, we can see with our bare eyes is visible light. which is only a tiny fraction of all electromagnetic waves the visible.
Longitudinal Wave	A sound wave is a LONGITUDINAL WAVE, which means that it oscillates in the same direction as it moves.
Expansion	the action of becoming larger or more extensive.
Compression	The INTENSITY of a sound wave is how much energy the sound wave carriers past a certain area.
Intensity	the INTENSITY of a sound wave is how energy the sound wave carries past a certain area.
Units of Sound	A sound wave can travel in matter only because it needs to transfer its energy from molecule to molecule.
Pitch	Our perception of sound wave frequency.
Analog Signal	carry information but vary continuously in both amplitude and frequency.
Digital Signal	send information as wave pulses, and communicate only through Is and Os, so the form that the in formation takes is much simpler.
