00:00 Introduction: Sound waves - Exercise (Part 3)
00:30 Question 41 to 50: Sound waves - Exercise (Part 3) : Chapter 11
Que. 41 In a resonance column experiment, a tuning fork of
frequency 400 Hz is used. The first resonance is observed
when the air column has a length of 20.0 cm and the
second resonance is observed when the air column has
a length of 62.0 cm. (a) Find the speed of sound in air.
(b) How much distance above the open end does the
pressure node form?
56:48 Question 51 to 60: Sound waves - Exercise (Part 3) : Chapter 11
Que. 51 A 30.0-cm-long wire having a mass of 10.0 g is fixed at
the two ends and is vibrated in its fundamental mode. A
50.0-cm-long closed organ pipe. placed with its open end near
the wire, is set up into resonance in its fundamental mode by
the vibrating wire. Find the tension in the wire. Speed of sound
in air 340 ms.
