Q. The speed of a wave on a string depends on __________.

एक तार पर तरंग की गति __________ पर निर्भर करती है।

Frequency only
केवल आवृत्ति

Tension and linear mass density
तनाव और रैखिक द्रव्यमान घनत्व

Amplitude only
केवल आयाम

Wavelength only
केवल तरंगदैर्घ्य

The wave speed $v$ on a stretched string is given by:
$v = \sqrt{\frac{T}{\mu}}$
where:
- $T$ = tension in the string
- $\mu$ = linear mass density (mass per unit length)
Frequency or amplitude does not affect the speed on a string.
