Following is given the equation of a travelling wave (all is SI units) (y=(0.02) 2 (10 t-5 x) ) Match the following columns. ( array l|l|l Column I & Column II (A) Speed of wave & (p) 10 (B) Frequency of wave & (q) 0.4 (C) Wavelength of wave & (r) 2 (D) Maximum particle speed & (s) 0.2 array )

Options

  1. A((A r, B q, C s, D p) )
  2. B((A p, B r, C s, D q) )
  3. C((A r, B p, C s, D q) )
  4. D((A r, B q, C s, D p) )

Correct answer

C. ((A r, B p, C s, D q) )

Step-by-step solution

Put wave in standard form (y(x, t)=A ( t-k x) ) (or (A (2 f t-k x)) ). Read off amplitude ( A ), angular frequency ( ) and wave number ( k ). Frequency: (f= 2 _ ). Wavelength: ( = 2 k ). Wave speed: (v= ^ k =f ). Maximum particle speed: (v_ =A ).
