Demonstrated the magnetic effect based on the direction of current.
AndreMarieAmpere
Formulated the principle behind electromagneticinduction.
Michael Faraday
Showed experimental evidence of electromagnetic waves and their link to light.
Heinrich Rudolf Hertz
Contributed in developing equations that showed the relationship of electricity and magnetism.
James Clerk Maxwell
Showed a current carrying wire behaves like a magnet.
Hans Christian Oersted
What produces electromagnetic waves?
Acceleratingelectrons
Are bundles of wave energy.
Photons
is the unit used to measure the frequency of waves.
Hertz
a ____ is a disturbance that transfers energy.
wave
He formulated the Electromagnetic Wave Theory which says that an oscillating electric current should be capable of radiating energy in the form of electromagnetic waves.
James Clerk Maxwell
Most EM waves are invisible to the eye but detectable. Only the ____ is seen by humans.
Visible light
State the EM waves from longest to shortest wavelength.
RMiVuXGa
What EM wave is sometimes called heat rays?
Infrared
a disturbance in a field that carries energy and does not require a medium to travel.
Electromagnetic wave
number of cycles a wave completes in one second; expressed in Hertz
Frequency
short for radio detecting and ranging. A way of detecting aircrafts and ships from a distance and estimating their locations.
Radar
receives radio waves and convert them back to sounds
Radio Receivers
attaches information to the radio signal by modulating it.
Radio Transmitter
the distance measured from one crest of a wave to the next crest or from one through to the second through.
Wavelength
who discovered X-rays?
Wilhelm Roentgen in 1895
The live audio and control rooms are connected by ____ for the exchange of audio and digital data signal during recording, mixing, and even editing of all audio-video elements digitally stored on hard drives.
cables
Used for "referencing" or for checking what the mix would sound like on the equipment.
headphone
Processor should be reasonably fast enough to record, edit, mix, store, and master a copy of the record.
computer unit
Microphones and musical instruments are plugged into this, which is connected to the computer.
audio interface
Used for playing some digital instruments, recording, adding effects, and mixing different sources of sound signals.
digital audio software (DAW)
Commonly known as speakers but these give a sound close enough to the real sound input.
studio monitor
Converts sound into electrical signal.
condenser or dynamic microphone
Used for connecting audio interface, microphones, studio monitors, and different instruments.
cables
Many of the recording technology are founded entirely or partially on the relationship between electricity and magnetism known as
electromagnetic induction
Devices that detect and convert audio inputs to electric outputs or vice versa are called
transducers
____ exert either a force of repulsion or attraction. same poles repel, opposite poles attract.
Magnets
If a force of ____ only is possible between an object and a magnet, then the object interacting with the magnet contains a ferromagnetic substance and is considered naturally magnetic.
force of attraction
If a force of ____ is also possible between an object and a magnet, then the object interacting with the magnet may also be a permanent magnet or a temporarily magnetized ferromagnetic material.
force of repulsion
Materials which are attracted by a magnet are known as ____ _____. Iron, cobalt, nickel, and many alloys of these materials like steel and alnico are magnetic.
magnetic materials
Can be used to make permanent or temporary magnets unlike the non-magnetic materials which cannot.
magnetic materials
One way of magnetization.
Stroking
He discovered the electromagnetism during a class demonstration that a current-carrying wire caused a nearby magnetized compass needle to deflect.
Hans Christian Oersted, a professor in the University of Copenhagen
He conducted his famous induction ring experiment showing that current can be produced by sources of changing magnetic fields. This is the key principle to practical generation of electricity.
Michael Faraday
are sources of electric fields which result in an attraction or repulsion of other nearby charges.
Charged particles
a fundamental electrical property that is either of positive or negative type to which the mutual attractions or repulsions between protons or electrons is attributed.
