NEET2002PhysicsWaves and SoundActual
A wave travelling in the positive x -direction with amplitude A =0.2 ~m , velocity v=360 ~ms ⁻¹ and wavelength =60 ~m , then the correct expression for the wave is:
Options
- Ay=0.2 [2 (6 t+ x 60 ) ]
- By=0.2 [ (6 t+ x 60 ) ]
- Cy=0.2 [2 (6 t- x 60 ) ]
- Dy=0.2 [ (6 t- x 60 ) ]
Correct answer
C. y=0.2 [2 (6 t- x 60 ) ]
Step-by-step solution
The general equation of wave travelling in x -direction is given as y=A [ 2 (V t-x) ] Where A=0.2 ~m , v=360 ~ms ⁻¹, =60 ~m The equation becomes aligned & y=0.2 [ 2 60 (360 t-x) ] & y=0.2 [2 (6 t- x 60 ) ] aligned
