JEE Main2011PhysicsWaves and SoundActual
The transverse displacement y(x, t) of a wave on a string is given by y(x, t)=e^ - (a x^2+b t^2+2 a b x t ) . This represents a
Options
- Awave moving in -x direction with speed b a
- Bstanding wave of frequency b
- Cstanding wave of frequency 1 b
- Dwave moving in +x direction with a b
Correct answer
A. wave moving in -x direction with speed b a
Step-by-step solution
y_ (x, t) =e⁻( a x+ b t)^2 v= b a Wave moving in - ve x -direction.
