Question

Differentiate the following:-
a) Compression and Rarefaction
. b) Transverse and Longitudinal waves
c) Crest and Trough​

Answer 1

Answer:

Explanation:

Difference in Compression and Rarefaction:However instead of crests and troughs, longitudinal waves have compressions and rarefactions. A compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.

Difference in Transverse and longitudinal wave:Transverse and Longitudinal waves? Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave. ... Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave

Difference in Crest and Trough:Crest and trough. A crest is the point on a wave with the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.

Answer 2

Answer:

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

=> When particles come together , they form a compression while When they move away, they form Rare fraction.

=> Compressions are regions of high density and high pressure while Rarefactions are regions of low density and low pressure.
