Question

Equation of a transverse wave pulse is
9
y =
(where x and y are in metre
3+ (x - 100)
and t is in second). The speed of the wave pulse
is
[NCERT Pg. 377]
(1) 3 m/s
(2) 5 m/s
(3) 10 m/s
(4) 100 m/s​

Answer 1

Answer:

Answer

Correct option is

D

y=

[(x−4.5t)

2

+3]

6

the equation of transverse wave pulse at t=o is y=6/(x

2

+3)

since the wave is travelling in positive x direction with speed 4.5 m/s so the position of pulse at t time is x−4.5×t

so the equation of pulse is y=

(x−4.5t)

2

+3

6

so the answer is D.
