Waves
Defines as a reflection of a sound wave.
An echo.
This type of current travels only in one, continues direction
Direct Current (DC)
Light waves are electromagnetic or mechanical?
Electromagnetic waves.
The two types of circuits include:
Parallel and series
Defines as how fast work is done.
Power
The unit of frequency is
Hertz (Hz)
is energy at rest, or the charged particles are not in motion
Electrostatics
What is it called when light bounces off matter?
Reflection
This type current moves back and forth with a changing magnetic field
AC- Alternating current
True or false: Power is directly proportional to work.
True
The number of oscillations completed in 1 sec.
Frequency
What are the three main charged particles:
Protons, Neutrons, Electrons
Defined as the bending of light waves when passing through media.
Refraction
This is defined as the electric flow between two objects that are transferring energy from one place to another
Electric current or current
Defined as when a force causes an object to move in the direction of the force.
Work
Wave speed depends on the
Medium
is the word that describes how hard it is for the electrical current to flow through and object.
Resistance
The process by which light energy is produced.
Emission
a property of matter that causes it to experience a force when near other electrically charged matter.
Electric charge
What is the equation form of work?
W = F x D
Work = Force x distance
Mechanical
Law that states the current in a circuit is directly proportional to the voltage impressed across the circuitIt also states that the current of the circuit is inversely proportional to the resistance
Ohm's law
The entire frequency range of electromagnetic waves is called ?
The electromagnetic spectrum
What is the formula for Ohm's law
Current = voltage/resistance
When you run up the stairs you do more work than you have when you walk up the stairs. T or F ?
False
