How high a wave it from the center line to the top of its peak and the bottom of its trough
Amplitude
Light waves travel in ___________ lines.
Straight
What is "a pathway for electricity to flow" called?
Circuit
What is "a push or a pull" called?
Force
To make the electromagnet stronger, you could add a ________.
Battery
Wavelength
When light bounces off other surfaces
Reflection
Open Circuit
When magnets pull TOGETHER, we say it...
Attracts
The energy of motion is called...
Kinetic Energy
How many cycles a wave makes in a period of time
Frequency
When light changes speed and direction
Refraction
What type of circuit is happening when electricity IS flowing?
Closed Circuit
When magnets push APART, we say it...
Repels
The energy of position is called...
Potential Energy
High pitched waves have a _______ frequency.
Low pitched waves have a _______ frequency.
High
Low
A repeating pattern of motion that transfers energy from place to place
Electromagnetic Waves
A circuit has a two wires. One wire is touching the negative end of the battery and the metal casing. The other wire is touching the positive end of the battery and the metal casing. Will the light bulb light?
No, the energy is coming in and out of the same outlet (metal casing). It would need one wire touching the bottom of the lightbulb.
What would happen to a magnet with N and N facing each other?
They would repel
When an object hits another object it is called...
Collision
LOUD sound waves have a ___________ amplitude.
Soft sound waves have a ____________ amplitude.
Higher
Lower
When it is completely dark and there is no light source, would you be able to see any objects in your room? Why or why not?
No you would not because there is no light source bouncing off the objects for you to see.
