Transverse & longitudinal waves
What are two types of waves?
100
The rate of flow of electric charges.
What is an electric current?
100
Vibration
What is the cause of sound?
100
Iron, nickel,cobalt, or mixture of these metals
What are the properties of magnets
100
when we see it we see all wavelengths of light at the same time.
What is white light?
200
A disturbance that transfers energy from place to another.
What is a wave?
200
When an atom has an overall positive or negative charge
What is an ion?
200
Mechanical & Electromagnetic waves
What are two sound waves?
200
Whether a material is magnetic or not depends on the materials atoms.
What is the cause of magnetism?
200
Light rays bounce off the surface when they strike.
What is reflection?
300
A measure of how far the particles in the medium move away from their normal rest position.
What is amplitude?
300
A conductor lets the charges move freely and an insulator doesn't let charges flow through it as easy.
What is the difference between the conductor and an insulator?
300
They are longitudinal.
What kind of waves are sound waves?
300
Magnetic field is stronger at the poles.
Where is the magnetic field the strongest?
300
A prism can split white light into its component colors, by seperating the colors by wavelength.
What can a prism do?
400
Medium
What do most waves need to travel energy?
400
They will repel.
What will happen when two like charges get close to each other?
400
A sound a wave moves the quickest in a solid.
Where does a sound wave move the quickest?
400
There will still be a north and a south pole.
What happens when you cut a magnet in half?
400
Em waves are measured by frequency or by wavelength.
How are EM waves measured?
500
Wavelength measures the length of one cycle, or repetition.
What does wave length measure?
500
The buildup of electric charges on an object.
What is static electricity?
500
The particles move right to left.
If a wave moves right to left in what direction do the particles move?
500
Any material that attracts iron or objects made of iron.
What are magnets?
500
When light is sent in many directions as it passes through a medium.
What is scattering?
