this is a property of matter that gives rise to all electric phenomena
What is a charge
200
these allow a transfer of energy
What are waves
200
this describes the distance between a crest and a trough
What is the amplitude
200
this is the type of scale volume follows
What is the logarithmic scale
200
these types of waves are generally used in medical instruments and cooking
What are microwaves
300
these have a mass of 9.10 x 10^-31 kilograms
What are electrons
300
the particles in this tyoe of wave move perpendicular
What are transverse waves
300
this is the distance between two successive points on a wave
What is a wavelength
300
this is the perception of frequency
What is pitch
300
these type of waves start at 300 GHz and end at 405 THz
What are infrared waves
400
the principle that the force between two point charges acts in the direction of the line between them and is directly proportional to the product of their electric charges divided by the square of the distance between them.
What is coulombs law
400
the particles in these types of waves move parallel to the direction of energy
What are longitudinal waves
400
this is the time required for one complete wavelength
What is the period
400
the average human can hear between these two frequencies
What is 20 Hz and 20 kHz
400
this start at 450 THz and end at 790 THz
What is visible light
500
the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.
What is conduction
500
these are special transverse waves where electric fields are perpendicular to magnetic fields
What are electromagnetic waves
500
these are the number of waves the pass per time
What is frequency
500
this is when a sound source moves and humans percieve that the sounds changes
