Sound Wave Theory, Speed of Sound, Interference and Beats 3 POWER POINTS WITH ANSWERS(39 PGS)

This product contains 3 Power Points on Sound Waves. These are suitable to use for a grade 11 physics class and combined are 39 pages long.

The 1st Power Point includes properties of sounds waves, mechanical waves, compressions, rarefactions, longitudinal compression waves, loudness, sound intensity, pitch, frequency, pure sounds, noise and rich sounds.

The 2nd Power Point includes calculating the speed of sound, calculating the air temperature, ultrasonic, infrasonic and audible sounds and an explanation of the doppler effect.

The 3rd Power Point includes beats, interference of sound waves. It also includes compressions, rarefactions, constructive interference, destructive interference, complex interference, resultant wave and beat frequency.

All the multiple choice questions, short answer questions, Power Points, worksheets, quizzes, labs and tests that I post are properly formatted and ready to print. They have been checked for mistakes and typos!
