For different independent waves are represented by
a) `Y_(1)=a_(1)sin omega_(1)t` , b) `Y_(2)=a_(2) sin omega_(2)t`
c) `Y_(3)=a_(3) sin omega_(3)t` , d) `Y_(4)=a_(4) sin(omega_(4)t+(pi)/(3))`
The sustained interference is possible due to

Options

A. `y_(1) = a_(1) sin omega_(1) t`
B. `y_(2) = a_(2)sin omega_(2) t`
C. `y_(3) = a_(3) sin omega_(3) t `
D. `y_(4) = a_(4) sin (omega_(4) t + (pi)/(3))`

Answer

D
