Following is given the equation of a travelling wave (all is SI units)
(y=(0.02) \sin 2 \pi(10 t-5 x))
Match the following columns.
(
)
| Column I | Column II |
| (A) Speed of wave | (p) 10 |
| (B) Frequency of wave | (q) 0.4 \pi |
| (C) Wavelength of wave | (r) 2 |
| (D) Maximum particle speed | (s) 0.2 |
Options
- A((A \rightarrow r, B \rightarrow q, C \rightarrow s, D \rightarrow p))
- B((A \rightarrow p, B \rightarrow r, C \rightarrow s, D \rightarrow q))
- C((A \rightarrow r, B \rightarrow p, C \rightarrow s, D \rightarrow q))
- D((A \rightarrow r, B \rightarrow q, C \rightarrow s, D \rightarrow p))
Correct answer
C. ((A \rightarrow r, B \rightarrow p, C \rightarrow s, D \rightarrow q))
Step-by-step solution
Put wave in standard form (y(x, t)=A \sin (t-k x)) (or (A \sin (2 f t-k x))).
Read off amplitude (), angular frequency () and wave number ().
Frequency: (f=).
Wavelength: (\lambda=).
Wave speed: (v=f \lambda).
Maximum particle speed: (v_{\max }=A ).
