The displacement y( in cm ) in case of a simple harmonic wave is given by y= 10 (2000 t- x 17 ) . The period and maximum velocity of the particles in the medium will respectively be
Options
- A10⁻³ ~s , 330 ~ms ⁻¹
- B) 10⁻⁴ ~s , 20 ~ms ⁻¹
- C10⁻³ ~s , 200 ~ms ⁻¹
- D10⁻² ~s , 2000 ~ms ⁻¹
Correct answer
C. 10⁻³ ~s , 200 ~ms ⁻¹
Step-by-step solution
Displacement equation in SHM is given as y= 10 (2000 t- x 17 ) cm Comparing with wave equation, y=a ( t-k x) aligned & We get, a= 10 cm = 10 10⁻² ~m & =2000 & 2 T =2000 & T=0.001 ~s T=10⁻³ ~s & aligned Maximum velocity, aligned v_ & = a=2000 10 10⁻² & =2 10^2=200 ~ms ⁻¹ aligned
