In a Kundt's tube experiment , with a wooden rod ` 170 cm` along , clamped at the middle , the lycopodium powder gets heated up at regular intervals of `13.4 cm` , the experiment being performed with air . If the frequency of vibrations be `1270 Hz` , find the velocity of sound in air and in the wooden rod.

To solve the problem, we will follow these steps: ### Step 1: Determine the wavelength in air In the Kundt's tube experiment, the distance between the points where the lycopodium powder gets heated corresponds to a quarter of the wavelength (λ/4) of the sound wave. Given that the distance is 13.4 cm, we can express this relationship mathematically. \[ \frac{\lambda}{4} = 13.4 \text{ cm} \] ...
