SOUND AND ULTRASONIC FREQUENCIES | ||
| 28.1 To identify the frequencies associated with ultrasonics. | ||
| 28.2 To describe the wave motion of ultrasonics. (COM) |
Explain the wave motion of ultrasonics. Compare it to other wave motions. | |
| 28.3 To explain the effect of a solid, liquid or gas on the speed of wave travel. |
Calculate the effect by relating the motion to the density of the medium. (NUM) | |
|
APPLICATION OF ULTRASONICS | |
| 28.4 To describe the use of ultrasonics in cleaning, flaw detection, welding, treatment of tumors and cancers, medical observations, fish detection and burglar alarm systems. (TL) |
