A plane wave is represented by
$x = 1.2 \sin(314t + 12.56y)$
Where x and y are distances measured along in x and y direction in meters and t is time in seconds. This wave has
Text Solution
Verified by ExpertsThe correct answer is:
C
The given equation representing a wave travelling along –y direction (because ‘+’ sign is given between t term and x term).
On comparing it with $x = A \sin(\omega t + ky)$
We get $k = \frac{2 \pi}{\lambda} = 12.56 \Rightarrow \lambda = \frac{2 \times 3.14}{12.56} = 0.5 \mathrm{m}$
