Question

1. The angular frequency of a particle in a
progressive wave in an elastic medium is 100T
rad s- and it is moving with a velocity of 200
ms-1. The phase difference between two
particles seperated by a distance of 20m is
a) 31.4 rad
b) p rad
Зп
c) rad
d) 36 rad​

Answer 1

Answer:

10 radians of phase difference

Explanation:

I explained in the form of picture posted

hope you understand this.

thank you .

Answer 2

Answer:

(a) 31.4 rad

Explanation:

given

angular frequency

$angular \: frequency( \omega )\ = 100\pi$

$velocity \ \: v = 200m s {^ - }$
