•              Sound is a Wave in air pressure

•              Waves bend toward areas where they move slower.

•              There is a depth in the ocean and an altitude in the air where Sound Waves move the slowest. These act as Sound Channels

•              When Waves meet, they “Interfere” with each other.

•              This can mean reinforcement or cancellation

•              Beats occur when two Waves gradually switch between reinforcement and cancellation. This gives rise to a gradually increasing or decreasing volume in Sound.

•              Musical Notes are Sound Waves of different Frequencies.

•              The Doppler Shift is a shift in the Frequency of the Wave due to the source (or observer) moving.
