A plane wave is represented by

x = 1.2\,\,\sin \left( {314t + 12.56y} \right)

. Where

x

and

y

are distances measured along in

x

and

y

direction in meters and

t

is time in seconds. This wave has

View answer and explanation

Correct option: C

A wavelength of

0.5\,\,m

and travels in 

- ve\,\,y

direction

Option C (A wavelength of

0.5\mathrm{ }\,m

and travels in 

- ve\mathrm{ }\,y

direction) is correct because the wavelength is calculated from the wave number, and the direction is determined by the sign in the wave equation.
