Which characteristic accounts for the fact that red lights are used in dark rooms and DO NOT expose negatives during developing?
small size
low energy
high energy
high velocity

low energy

Explanation:

They use low amounts of energy and don't affect the developing process. The chemicals used and the negative film are affected by regular light and it can destroy the pictures and the development. The red light prevents chemical processes that destroy the photos and that's why it is used in dark rooms.

what experimental evidence led scientists to change from the previous model to this one?

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.

cathode rays were bent in the same way whenever a magnet was brought near them.
