State any five differences between longitudinal ad transverse waves
Asked by | 03 Mar, 2012, 11:55: AM
answered-by-expert Expert Answer
In a longitudinal wave, the motion of the medium is parallel to the direction of the wave . This means that the particles move left and right which in turn makes the other particles start to oscillate. Sound waves are longitudinal waves.
Another example of a longitudinal wave is a P wave or primary wave during an earthquake. P waves are also known as compressional waves, because of the pushing and pulling they do. 

A transverse wave is a wave in which the motion of the medium is a right angles to the direction of the wave.
A wave on a rope is a transverse wave. Light and other electromagnetic waves are also transverse waves.
Another type of transverse wave is the S wave or secondary wave, which is the second wave we feel in an earthquake.

(3 X 3 = 9) CASE STUDY QUESTION 26. Ultrasounds can be used to detect cracks and flaws in metal blocks. Metallic components that are generally used in construction of big structures like buildings, machines and also scientific equipment. The cracks or holes inside metal blocks, which are invisible from outside, reduce the strength of the structure. Ultrasonic waves are allowed to pass through the metal block and detectors are used to detect the transmitted waves. If there is even a small defect, the ultrasound gets reflected back indicating the presence of flaw or defect. Clearly indicated in the figure Defect or flaw Ultrasound Detectors Metal Block (a) The transmitter sends an ultrasound wave of speed 5960m/s through a long steel bridge and a block reflects it back after 0.02s. how far the block in the metal bridge is from the transmitter. (b) With the above property of ultrasound waves, Can ultrasonic waves be used in the medical field? If so, how and give one use in the medical field to justify your answer? (c) Give two practical applications of reflection of sound waves?
