SATHEE: Wave Motion 1 Question 15

Wave Motion 1 Question 15

15. A travelling wave has the frequency $v$ and the particle displacement amplitude $A$ . For the wave the particle velocity amplitude is ….. and the particle acceleration amplitude is

$(1983, 2 M)$

Show Answer

Answer:

Correct Answer: 15. $2 π v A, 4 π^{2} v^{2} A$

Solution:

(a) Particle velocity amplitude means maximum speed

$= ω A = 2 π v A$

(b) Particle acceleration amplitude

$= ω^{2} A = 4 π^{2} v^{2} A$
