QAIPM-2002-Ph-2830: NEET 2002 Physics - Class 11 AIPM-2002-Ph-2830 Solution: A wave travelling in positive X-direction with a = 0.2 \(…

A wave travelling in positive X-direction with a = 0.2

\text{ms}^{-2}

, velocity = 360

\text{ms}^{-1}

and

\lambda

= 60 m, then correct expression for the wave is

Multiple Choice Options

A $y=0.2\sin[2\pi(6t+\frac{x}{60})]$
B $y=0.2\sin[\pi(6t+\frac{x}{60})]$
C $y=0.2\sin[2\pi(6t-\frac{x}{60})]$
D $y=0.2\sin[\pi(6t-\frac{x}{60})]$

Step-by-Step Verified Solution

The equation of progressive wave travelling in positive x-direction is given by y = a sin _ 2 � _ ( v t _ x ) Here a = 0.2 m, v = 360 m/sec, _ = 60 m _ y = 0.2 sin _ 2 � 60 ( 360 t _ x ) = 0.2 s i n [ 2 � ( 6 t _ x 60 ) ]
