JEE Main2008PhysicsWaves and SoundActual
A wave travelling along the x -axis is described by the equation y(x, t)=0.005 ( x- t) . If the wavelength and the time period of the wave are 0.08 ~m and 2.0 ~s , respectively, then and in appropriate units are
Options
- A=25.00 , =
- B= 0.08 , 2.0
- C= 0.04 , = 1.0
- D=12.50 , = 2.0
Correct answer
A. =25.00 , =
Step-by-step solution
y=0.005 ( x- t ) comparing the equation with the standard form, aligned & y=A [ ( x - t T ) 2 ] & 2 / = and 2 / T= & =2 / 0.08=25.00 & = aligned
