According to their frequencies, waves are separated into three categories:
(1) Audible or sound waves : Range 20 Hz to 20 KHz. These are formed by vibrating bodies like as vocal cords, membrane or stretched strings.
(2) Infrasonic waves : Frequency lie below 20 Hz.
Example : waves formed during earth quake, ocean waves etc.
(3) Ultrasonic waves : Frequency greater than 20 KHz. Human ear cannot listen these rays, certain creatures such as dog, bat and mosquito show result to these.
The stress at which the specimen breaks or reptures ultimately is known as ultimate strength. We also called this TENSILE STRENGTH .
