Module 4 Honors Review

What is the doppler effect?

• An addedum technology built to help withstand global warming of other planets.

• an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other

• A technology only used for meterology

• The effect of neurotransmitters in the brain which affect olverall mood.
