Question A wave of frequency \( 100 \mathrm{~Hz} \) travels along a string towards its fixed end. When this wave travels back, after reflection, a node is formed at a distance of 10 \( \mathrm{cm} \) from the fixed end. The speed of the wave (incident and reflected) is:
(A) \( 5 \mathrm{~m} / \mathrm{s} \)
(B) \( 10 \mathrm{~m} / \mathrm{s} \)
(C) \( 20 \mathrm{~m} / \mathrm{s} \)
(D) \( 40 \mathrm{~m} / \mathrm{s} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
