# NEET Physics Waves Questions Solved

When a string is divided into three segments of lengths  the fundamental frequencies of these three segments are  respectively. The original fundamental frequency (v) of the string is

(a) $\sqrt{v}=\sqrt{{v}_{1}}+\sqrt{{v}_{2}}+\sqrt{{v}_{3}}$

(b) $v={v}_{1}+{v}_{2}+{v}_{3}$

(c) $\frac{1}{v}=\frac{1}{{v}_{1}}+\frac{1}{{v}_{2}}+\frac{1}{{v}_{3}}$

(d) $\frac{1}{\sqrt{v}}=\frac{1}{\sqrt{{v}_{1}}}+\frac{1}{\sqrt{{v}_{2}}}+\frac{1}{\sqrt{{v}_{3}}}$
