JEE Main2003PhysicsWaves and SoundActual
The displacement y of a wave travelling in the x -direction is given by y=10⁻⁴ (600 t-2 x+ 3 ) metres where x is expressed in metres and t in seconds. The speed of the wave-motion, in ms ⁻¹ , is
Options
- A300
- B600
- C1200
- D200
Correct answer
B. 600
Step-by-step solution
y=10⁻⁴ (600 t-2 x+ 3 ) . Comparing it with standard equation y=A (v t-k x) ; v=600 m / s
