Velocity of sound in air is 300 m/s. Then the distance between two suc...
Velocity of sound in air= 300m/s =300×100=30000 cm/s
And frequency = 1000 hz
So, wavelength = Velocity/frequency
= 30000/1000= 30
Distance = wavelength/2
=30/2 = 15

The distance between two successive nodes in a stationary wave can be determined using the formula:

\(d = \frac{v}{2f}\)

where:
- \(d\) is the distance between two successive nodes
- \(v\) is the velocity of sound in air
- \(f\) is the frequency of the wave

In this case, we are given that the velocity of sound in air is 300 m/s and the frequency of the wave is 1000 Hz. Let's substitute these values into the formula to find the distance between two successive nodes.

Calculation:
\(d = \frac{300}{2 \times 1000}\)
\(d = \frac{300}{2000}\)
\(d = 0.15\) m

Thus, the distance between two successive nodes is 0.15 m.

Converting the distance to centimeters:
\(0.15 \, \text{m} = 0.15 \times 100 \, \text{cm}\)
\(= 15 \, \text{cm}\)

Therefore, the correct answer is option B) 15 cm.
