Question
Explain the reflection of transverse and longitudinal waves from a denser medium and a rared medium.
Solution
● Transverse waves -
- Transverse waves consists of crests and troughs.
- In denser medium after reflection, phase difference is π. Therefore, crest travels as trough and trough travels as crest.
- In rarer medium after refection, phase difference is 0. Therefore, crest travels as crest and trough travels as trough.
● Longitudinal waves -
- Longitudinal waves consist of compression and rarefaction.
- In denser medium after reflection, phase difference is π. Therefore, compression becomes compression and rarefaction as rarefaction.
- In rarer medium after reflection, phase difference is 0. Therefore, compression becomes rarefaction and rarefaction as compression.
