A wave is given by Y=3 2 ( t 0.04 - x 0.01 ) where Y is in cm . Frequency of the wave and maximum acceleration will be ( ^2=10 )

Options

  1. A100 ~Hz , 4.7 10^4 ~cm / s ^2
  2. B50 ~Hz , 7.5 10^3 ~cm / s ^2
  3. C25 ~Hz , 4.7 10^4 ~cm / s ^2
  4. D25 ~Hz , 7.5 10^4 ~cm / s ^2

Correct answer

D. 25 ~Hz , 7.5 10^4 ~cm / s ^2

Step-by-step solution

y=3 2 ( t 0.04 - x 0.01 ) Comparing with standard wave equation, array ll y = A 2 ( ft x ) t 0.04 f =25 ~Hz =2 f = 2 0.04 a _ = ^2 ~A = 4 ^2 3 (0.04)^2 =7.4 10^4 ~cm / s ^2 7.5 10^4 ~cm / s ^2 array
