What does a wave always transfer?
Energy
Define Refraction
What are the key components of a circuit ?
- battery (power source)
- conductive wires
- load (light bulb)
- switch
What is a constant ?
What is the equation for Ohm's Law?
V=IR
What are the two types of waves?
Mechanical & Electromagnetic Waves
What property does amplitude impact?
Volume
There is a circuit with all the components but the light bulb is not turning on, why do you think ?
- the circuit is open which is not allowing electrons/ electricity to flow through from the battery to the wires and to the load to turn it on.
In Ohm's law equation, what does I stand for?
Current
Electromagnetic wave = light wave
What property does wavelength impact?
Color
Current & Resistance have what type of relationship?
Inverse relationship
- when one increases, the other decreases
- when one decreases, the other increases
What is an independent variable ?
A variable that is purposefully manipulated/changed in the experiment
Define electric force
When objects interact with each other based on their charge
What are the key components to drawing a wave diagram?
- start at 0
- scale (+/-)
- Dashed line
- correct amplitude
- correct frequency
What property does frequency impact?
Pitch
Voltage & current have what type of relationship?
Direct relationship
- when one increases, the other increases
- when one decreases, the other decreases
The height of bean plants depends on the amount of they receive
What is the independent variable in this scenario?
The amount of water the plants receive
Two protons are coming near one another. What interaction is going to happen? Why?
Repulsion because they are like charges
Electromagnetic waves do not require a medium
Mechanical waves do require a medium
Define absorption
Occurs when a wave hits a surface and the energy of the wave is taken up by the surface
The brightness of lightbulbs on a series circuit will _______ as you increase the number of lightbulbs.
a. increase
b. decrease
c. remain constant
decrease
An investigation found that more bushels of potatoes were produced when the soil was fertilized more.
What is the dependent variable?
The amount of bushels that were produced
Nothing is going to happen because neutrons do not have any charge, so neither repulsion or attraction
