Correct answer: C. (iii) and (iv)

For sustained interference fringes to be produced, the superposing light waves must be coherent. Coherent waves must have the same frequency and a constant phase difference with respect to time. The angular frequency of wave (i) is . The angular frequency of wave (ii) is . The angular frequency of wave (iii) is 2 . The angular frequency of wave (iv) is 2 . Waves (i) and (ii) have the same frequency and a constant phase difference . Waves (iii) and (iv) have the same frequency 2 and a constant phase difference 2 . T
