Beath High School - Int 1 Physics2 amplifier amplifier to frequency amplitude decibels (dB) emitted frequency a device which turns a small amplitude electrical signal into a larger amplitude signal a measure of the energy of the wave the units used to measure the loudness of a sound signals or energy sent out from the source the number of waves or vibrations in one second

Beath High School - Int 1 Physics3 hertz hertz to noise pollution laser loudspeaker microphone noise pollution the unit of frequency a concentrated source of light made up of only one colour changes electrical energy into sound energy changes sound energy into electrical energy unacceptable levels of unwanted sound

Beath High School - Int 1 Physics4 octave octave to speed pitch sonar sound level speed a sound which is twice the frequency of another is said to be one octave higher how high or low a sound is apparatus emitting high frequency sounds used by ships and fishermen to locate objects underwater how loud a sound or noise is how fast energy travels from one place to another

Beath High School - Int 1 Physics5 trace trace to vibration tuning fork ultrasound vacuum vibration line or wave seen on an oscilloscope (CRO) two pronged metal fork used to make a sound of a single frequency a sound of frequency greater than Hz, a sound above the range of human hearing an area of space where there are no particles of any type present rapid to-and- fro motion

Beath High School - Int 1 Physics6 voltage gain voltage gain to volume volume how much bigger the output voltage of an amplifier is than the input voltage: voltage gain = output voltage/ input voltage how loud a sound is
