100
The rate at which light or any other form of energy flows through a given area of space.
What is intensity?
100
An image that forms at a point from which light rays appear to come but do not actually come.

100
Bends when it changes mediums.
What is light?
100
An effect in which the vibration of one object causes the vibration of another object at a natural frequency.
What is resonance?
200
The perceived highness or lowness of a sound, depending on the frequency of sound waves

A change in the size of an image compared with the size of an object.
What is magnification?
500
With this doctors can safely view organs inside the body without having to perform surgery.
What is sonograms?
500
Can be used to measure the heat that objects radiate and then create images that show temperature variations.
