Sound Intensity and Sound Level
This program covers the important topic of sound intensity and sound level in Physics. We begin by discussing how sound waves carry energy and how it is sometimes convenient to discuss the energy carried by a wave in terms of its sound intensity or sound level. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long term memory.
