100

Defines as a reflection of a sound wave.

An echo.

100

This type of current travels only in one, continues direction

Direct Current (DC)

100

Light waves are electromagnetic or mechanical?

Electromagnetic waves.

100

The two types of circuits include:

Parallel and series

100

Defines as how fast work is done.

Power

200

The unit of frequency is

Hertz (Hz)

200

 is energy at rest, or the charged particles are not in motion

Electrostatics

200

What is it called when light bounces off matter?

Reflection

200

This type current moves back and forth with a changing magnetic field

AC- Alternating current

200

True or false: Power is directly proportional to work.

True

300

The number of oscillations completed in 1 sec.

Frequency

300

What are the three main charged particles:

Protons, Neutrons, Electrons

300

Defined as the bending of light waves when passing through media.

Refraction

300

This is defined as the electric flow between two objects that are transferring energy from one place to another

Electric current or current

300

Defined as when a force causes an object to move in the direction of the force.

Work

400

Wave speed depends on the 

Medium

400

 is the word that describes how hard it is for the electrical current to flow through and object.

Resistance

400

The process by which light energy is produced.

Emission

400

 a property of matter that causes it to experience a force when near other electrically charged matter.

Electric charge

400

What is the equation form of work?

W = F x D

Work = Force x distance

500
What type of wave are sound waves? Electromagnetic or mechanical waves?

Mechanical

500

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

500

The entire frequency range of electromagnetic waves is called ?

The electromagnetic spectrum

500

What is the formula for Ohm's law

Current = voltage/resistance

500

When you run up the stairs you do more work than you have when you walk up the stairs. T or F ?

False
