IIT JEE , AIEEE Forum - Physics , General - question on waves: at t = 0, y = 1/(1 + x^2) and at t = 2, y = 1/(1 + (x

Greatdreams

For a equation to represent a wave,

y ( x,t ) = f (ax

bt )

at t = 0 , y = 1/1+x²

at t = 2 , y = 1/1+(x-1)²

the wave is of the form : y = a/[ b + (x-vt)² ]

So if you compare the equations ,

we get v t = 1 , so t = 2, hence velocity = 0.5 m/s in +ve

direction

I was myself confused with this thing till i finally got this

general term in Arihant obj physics book.

Check the attached file you will see that the pulse moves

in the positive direction.
