Answer:
If the end of the tube is uncovered such that the air at the end of the tube can freely vibrate when the sound wave reaches it, then the end is referred to as an open end. If both ends of the tube are uncovered or open, the musical instrument is said to contain an open-end air column.

The speed of sound in the straw will be 87.5 m/sec. It is the product of frequency and the wavelength.
Frequency is defined as the number of repetitions of a wave occurring waves in 1 second.
The given data in the problem is;
[tex]\lambda[/tex] is the length = 25 cm= 25 ×10⁻²
f is the frequency = 350 Hz
v is the speed of sound in the straw = ?
Frequency is given by the formula as,
[tex]\rm v = \lambda \times f \\\\\ \rm v = 25 \times 10^{-2} \times 350 \\\\\ v= 87.5 \ Hz[/tex]
Hence, the speed of sound in the straw will be 87.5 m/sec.
