The equation of stationary wave is : y=2 a ( 2 n t ) ( 2 x ) . Which of the following is NOT correct :

Options

  1. AThe dimensions of n / is [T]
  2. BThe dimensions of n is [ LT ⁻¹ ]
  3. CThe dimensions of x is [L]
  4. DThe dimensions of nt is [L]

Correct answer

A. The dimensions of n / is [T]

Step-by-step solution

Comparing the given equation with standard equation of standing 2 n = & 2 =k aligned & [ n ]=[ ]= T ⁻¹ & [ nt ]=[ ]= L & [ n ]=[ ]= LT ⁻¹ & [ x ]=[ ]= L aligned
