In a resonance air column apparatus, the first and second resonance positions were observed at 18cm and 56cm respectively. The frequency of the tuning fork used was 480 Hz. Calculate the velocity of sound in air and end correction of the tube.
What are the structures and functions of sclerenchyma?
Describe Laplace's correction in Newton's formula for velocity of sound in air. Also discuss the effect of temperature and pressure in the velocity of sound in air.
