This
section will answer many questions e.g. Why is sound a longitudinal wave? Why can't sound travel through a vacuum?
Know that and understand that sound waves and
some mechanical waves are longitudinal, and cannot travel through a vacuum. Describe an experiment to measure the speed of sound. What are the uses of ultrasound? Why can some earthquake
waves be the same as sound waves?
