The Electromagnetic Spectrum
The range of waves from radio to gamma is called the ______________ _____________ .
The Electromagnetic Spectrum
Hot rises and cold sinks happens in this kind of energy transfer.
Convection
This type of material allows heat and energy to pass through it. Metal is a good one.
Conductor
A lamp includes which energy transformations?
Electric ---> Thermal and Radiant

They speed up
True of False
Microwaves are higher on the electromagnetic spectrum than X-rays
False
This occurs when you put cold ice cream in your mouth.
Conduction
When light passes through a material but bends in the process.
Refraction
An electric car has three major energy transformations. What are they?
Electric --> Chemical ---> Mechanical
The frequency of sound waves is called _______.
Hertz (Hz)
When the frequency of a wave increases, what happens to the wavelength?
They get shorter
The total energy of all the particles in something.
Thermal Energy
The sum of the potential energy and the kinetic energy.
Mechanical Energy

potential energy
Sound waves travel through a series of ____________.
vibrations
High levels of these waves can damage your skin and lead to skin cancer.
Ultraviolet waves
Heat transfer through Electromagnetic Waves.
Radiation
In an experiment, the variable that is changed each time to produce different results.
Independent Variable
What is the law of Energy Conservation?
Energy cannot be created or destroyed. Only changed.

diamond
These waves carry phone signals.
Microwaves
This is a measure of the average kinetic energy in an object.
