JEE Main2014PhysicsWaves and SoundActual
A transverse wave is represented by : y = 1 0 π sin 2 π T t - 2 π λ x For what value of the wavelength the wave velocity is twice the maximum particle velocity?
Options
- A40 cm
- B60 cm
- C10 cm
- D20 cm
Correct answer
A. 40 cm
Step-by-step solution
w a v e velocity = n λ ( V p ) m a x = a ω n λ = 2 a 2 π n λ = 2 ( a ) 2 π = 2 . 10 π . 2 π = 40 cm
