Explanation

Two waves of same frequency and amplitude meet at a point where they are 180⁰ out of phase. Which of the following is correct?

a: They superimpose, resulting in zero intensity Explanation

Explanation

b: Their amplitudes subtract, resulting in zero amplitude Explanation

Explanation

c: Destructive interference occurs Explanation

Explanation

d: Their energy at that point disappear and thus the energy of the waves after interference is half that of the original waves Explanation
