Two waves having equation x₁ = $$a$$sin($$\omega $$t $$-$$ kx + $$\phi $$₁), x₂ = asin($$\omega $$t $$-$$kx + $$\phi $$₂). If in the resultant wave the frequency and amplitude remain equal to amplitude of superimposing waves, the phase difference between them is

$${\pi \over 6}$$

$${{2\pi } \over 3}$$

$${\pi \over 4}$$

$${\pi \over 3}$$

A string is cut into three parts, having fundamental frequencies n₁, n₂, n₃ respectively. Then original fundamental frequency n related by the expression as

$${1 \over n} = {1 \over {{n_1}}} + {1 \over {{n_2}}} + {1 \over {{n_3}}}$$

$$n = {n_1} \times {n_2} \times {n_3}$$

n $$=$$ n₁ + n₂ + n₃

$$n = {{{n_1} + {n_2} + {n_3}} \over 3}$$
