MCQ
A wave is represented by the equation : $y = a\sin (0.01x - 2t)$ where $a$ and $x$ are in $cm$. velocity of propagation of wave is .... $cm/s$
- A$10$
- B$50$
- C$100$
- ✓$200$
✓
Answer
Correct option: D.
$200$
d
(d) $v = \frac{\omega }{k} = \frac{{{\rm{Co}} - {\rm{efficient}}\;{\rm{of}}\;t}}{{{\rm{Co}} - {\rm{efficient}}\;{\rm{of}}\;x}} = \frac{2}{{0.01}} = 200\,cm/sec $.
(d) $v = \frac{\omega }{k} = \frac{{{\rm{Co}} - {\rm{efficient}}\;{\rm{of}}\;t}}{{{\rm{Co}} - {\rm{efficient}}\;{\rm{of}}\;x}} = \frac{2}{{0.01}} = 200\,cm/sec $.
