Four waves are expressed as
1. `y_1=a_1 sin omega t`
2. `y_2=a_2 sin2 omega t`
3. `y_3=a_3 cos omega t`
4. `y_4=a_4 sin (omega t+phi)`
The interference is possible between

Four different independent waves are represented by y_1=a_1 sin omegat y_2=a_2 sin 2 omega t y_3=a_3 cos omega t y_4=a_4 sin( omega t+lamda/3) With which of two waves interference is possible

Four light waves are represented by (i) y=a_1sin omegat (ii) y=a_2 sin (omega t+varphi) (iii) y=a_1sin 2 Omega t (iv) y=a_2sin 2(omegat+varphi) Interference fringes may be observed due to superposition of

Two waves are represented by the equations y_1=a sin omega t and y_2=a cos omegat . The first wave

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

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

y_1 =4sin( omega t + kx), y2 = -4 cos( omega t + kx), the phase difference is

Two wave are represented by equation y_(1) = a sin omega t and y_(2) = a cos omega t the first wave :-
