These waves are of same frequencies and they are coherent

Q. Four light waves are represented by :-
$(i) y = a_{1} s in (3 ω t)$
$(ii) y = a_{2} s in (ω t + ϕ)$
$(iii) y = a_{1} s in (2 ω t)$
$(i v) y = a_{2} s in [2 (ω t + ϕ)]$
Interference fringes may be observed due to superposition of:

$(i)$ and $(ii)$

$(i)$ and $(iii)$

$(ii)$ and $(i v)$

$(iii)$ and $(i v)$
