Assertion : Transverse waves travel through air in an organ pipe.
Reason : Air possesses only volume elasticity.
The correct option is D, if the assertion is false but the reason is true.
Explanation:
- An organ pipe is a musical instrument that produces sound by the vibration of air inside it. It consists of a tube or cylinder with one or both ends open, allowing air to enter and exit the pipe.
- When a musical note is played on an organ pipe, it produces sound waves that travel through the air inside the pipe.
- Sound waves can be classified as either transverse or longitudinal waves. Transverse waves are characterized by the oscillation of particles perpendicular to the direction of wave propagation, while longitudinal waves are characterized by the oscillation of particles parallel to the direction of wave propagation.
- In the case of an organ pipe, the sound waves produced are longitudinal waves. The air particles inside the pipe oscillate back and forth in the same direction as the wave propagation.
- The reason given in the statement is that air possesses only volume elasticity. Elasticity is the property of a material to deform under the influence of an external force and return to its original shape when the force is removed. Volume elasticity refers to the ability of a material to change its volume under the application of external pressure and return to its original volume when the pressure is released. Air possesses volume elasticity, which allows it to compress and expand in response to changes in pressure.
- However, the reason does not provide a correct explanation for the assertion. The assertion states that transverse waves travel through air in an organ pipe, but this is incorrect. The waves produced in an organ pipe are longitudinal waves, not transverse waves. Therefore, the assertion is false.
- The reason given is true, as air does possess volume elasticity. However, it does not explain why transverse waves would travel through air in an organ pipe, as the waves produced in an organ pipe are longitudinal waves.
- Hence, the correct option is D, if the assertion is false but the reason is true.
