Question

4. A) What is the difference between a transverse wave and a longitudinal wave? Explain Support your explanations by giving examples of these types of waves from everyday life? (4 Points.) B) A cork on the surface of a lake is observed to move up and down a total vertical distance of 40 cm (lowest to highest point). The cork completes 2 cycles in 5 seconds. The waves on the lake seem to be an endless succession of identical crests. If the distance between two adjacent crests is measured to be 6 m, determine 0) the amplitude of the wave, (2 Points.) (iül) the frequency of the wave, and (2 Points.) (ii) the speed of the wave. (2 Points.)

Explanation / Answer

Transverse wave- This wave is formed when the particles of the medium vibrate to and fro perpendicular to the direction of motion of the wave.

Example: A stone dropped in water forms ripples.

Longitudinal wave- This wave is formed by the alternate compression and rarefaction of the medium.

Example: sound waves
