1. Sound Waves – PPT To attract the attention of students to the subject, daily life animations were used. This resource includes 60 slides; - (questions with Answer key) - Physics around us... Everything is ready to be used or easily edited to suit your learners. You should install these Fonts for this document; (Marker Felt aAND Tempus Sans ITC) With this PPT, Candidates should be able to: (a) describe the production of sound by vibrating sources. (b) describe the longitudinal nature of sound waves and describe compression and rarefaction. (c) state the approximate range of audible frequencies for the healthy human ear as 20 Hz to 20 000 Hz. (d) explain why a medium is required in order to transmit sound waves and describe an experiment to demonstrate this. (e) describe a direct method for the determination of the speed of sound in air and make the necessary calculation. (f) state the order of magnitude of the speeds of sound in air, liquids, and solids. (g) explain how the loudness and pitch of sound waves relate to amplitude and frequency. (h) describe how the reflection of sound may produce an echo. (i) describe how the shape of a sound wave as demonstrated by an oscilloscope is affected by the quality (timbre) of the sound wave. (j) define ultrasound. (k) describe the uses of ultrasound in cleaning, quality control, and pre-natal scanning. 2.
