Question

Which type of wave is produced in a resonance tube?
A. longitudinal
B. transverse
C. transverse stationary
D. longitudinal stationary

Answer 1

Resonance tube is used to observe the phenomenon of resonance in an open ended cylindrical tube to determine the velocity of sound in air. Resonance tubes produce sound waves. Find out whether sound waves are longitudinal or transverse or transverse stationary or longitudinal stationary.

Complete step by step answer:
A resonance tube is a hollow cylindrical tube partially filled with water and forced into vibration by a tuning fork. The tuning fork is the object that forces the air inside of the resonance tube into resonance and produces sound waves.
Longitudinal waves are the waves in which the vibrations are parallel to the direction of wave travel. Longitudinal waves have compressions and rare fractions. Examples of longitudinal waves are sound waves, ultrasound waves and seismic P-waves .
Transverse waves are the waves in which the vibrations are perpendicular to the direction of waves. Transverse waves have peaks and troughs. Examples of transverse waves are electromagnetic waves such as light waves, microwaves, seismic S-waves and radio waves.
Stationary waves have the same amplitude and wavelength and travel along a straight line in opposite directions superimposing on each other. There are two types of stationary waves i.e. transverse and longitudinal. These waves are stationary. But the waves produced in a resonance tube are not stationary.
Resonance tubes produce sound waves and sound waves are just longitudinal waves.
Therefore, Option A is correct.

Note: Resonance is causing it to resound or reverberate. Resonance only occurs when the first object is vibrating at the natural frequency of the second object.
