What characteristic is responsible for our brain being able to distinguish different colors? Options:
Each color is a different wavelength of light
Each color of light has a different amplitude
Light changes colors as it goes through the different mediums between the air and our eyes
Each color has a different speed

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.
