Questions
A plane wave is represented by
Where x and y are distances measured along in x and y direction in meters and t is time in seconds. This wave has
a
A wavelength of 0.25 m and travels in + ve x direction
b
A wavelength of 0.25 m and travels in + ve y direction
c
A wavelength of 0.5 m and travels in – ve y direction
d
A wavelength of 0.5 m and travels in – ve x direction
detailed solution
Correct option 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=Asin ω t+kyWe get k=2πλ=12.56⇒λ=2×3.1412.56=0.5 mTalk to our academic expert!
