This is something that is changed during an experiment
What is a variable
All energy travels as this
What are waves
This type of object allows light to pass through without making it blurry
What is transparent
This is the lowest energy wave
What is Radio
This is the experimenter's "Best guess" and will be tested in an experiment
What is hypothesis
What is a scientific question
This is the measure of rate of time between wave peaks
What is frequency
This type of material absorbs light that hits it
what is opaque
This is the highest energy wavelength
What are gamma rays
This is the group that is being experimented on
What is the test group
This is the part of the experiment we are testing for and can change
what is an independent variable
This is the distance between wave peeks or troughs
What is Wavelength
This type of lens causes lightwaves to spread out
What is Convex
This happens when light passes from one medium to another
What is refraction
this is also known as the outcome variable
What is dependent variable
this is the part of the experiment that produces a measurable result
What is the dependent variable
This is the strength of the wave
What is amplitude
This type of lens is thinner in the middle than the edges
What is Concave
These are the colors of the portion of the Electromagnetic Spectrum humans can see
What is Red, Orange, Yellow, Green, Blue, Indigo, and Violet
This is also known as the test variable
What is independent variable
This is the group that nothing out of the ordinary is being done to, and is being used for comparison
What is the control group
This is the spot that a lens or mirror focusses light to
What is focal point
This type of material allows light to pass, but makes objects blurry
What is transluscent
Light refracts when it passes from one medium to another because it does this
A single experiment should test this number of variables
what is only one
