Wave length & Amplitude
the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
Wave length & Amplitudethe maximum extent of a vibration or oscillation, measured from the position of equilibrium.
Types of Sound Waves Longitudinal: Like P-waves
Mechanical: Like Surface Waves (ex: water)
Transverse: Like S-waves Types of Waves INFO

PitchThe sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave
Doppler Effect The Doppler
effect is the change in frequency of a wave (or other periodic event) for an observer moving relative to its source
Ear Diagram & Info anvil - (also called the incus) a tiny bone that passes vibrations from the hammer to the stirrup.
cochlea - a spiral-shaped, fluid-filled inner ear structure; it is lined with cilia (tiny hairs) that move when vibrated and cause a nerve impulse to form.
eardrum - (also called the tympanic membrane) a thin membrane that vibrates when sound waves reach it.
Eustachian tube - a tube that connects the middle ear to the back of the nose; it equalizes the pressure between the middle ear and the air outside. When you "pop" your ears as you change altitude (going up a mountain or in an airplane), you are equalizing the air pressure in your middle ear.
hammer - (also called the malleus) a tiny bone that passes vibrations from the eardrum to the anvil.
nerves - these carry electro-chemical signals from the inner ear (the cochlea) to the brain.
outer ear canal - the tube through which sound travels to the eardrum.
pinna - (also called the auricle) the visible part of the outer ear. It collects sound and directs it into the outer ear canal
semicircular canals - three loops of fluid-filled tubes that are attached to the cochlea in the inner ear. They help us maintain our sense of balance.
stirrup - (also called the stapes) a tiny, U-shaped bone that passes vibrations from the stirrup to the cochlea. This is the smallest bone in the human body (it is 0.25 to 0.33 cm long).
Electromagnetic Waves Electromagnetic waves are waves
which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.
Polarized Light
Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization.

Photoelectric Effect The photoelectric effect is the
observation that many metals emit electrons when light shines upon them. Electrons emitted in this manner can be called photoelectrons.
Photon Photons are tiny little particles of light,
far too small to see individually
Thermogram
an instrument that produces a trace or image representing a record of the varying temperature or infrared radiation over an area or during a period of time.
Electromagnetic Spectrum The electromagnetic spectrum is the
range of all possible frequencies of electromagnetic radiation
Visible LightElectromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm
-See previous slide for spectrum
Ultraviolet Rays Radiation in the part of the electromagnetic spectrum
where wavelengths are just shorter than those of ordinary, visible violet light but longer than those of x-rays.
X-Rays-an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light.
Gamma Rays penetrating electromagnetic radiation of
a kind arising from the radioactive decay of atomic nuclei.
Amplitude modulation the modulation of a wave by varying its
amplitude, used chiefly as a means of radio broadcasting, in which an audio signal is combined with a carrier wave.
Frequency Modulation the modulation
of a radio or other wave by variation of its frequency, especially to carry an audio signal.
