Bcz Sound is pass through the medium(solid,liquid,gas)..... so frequency is does not depend on the medium.

Frequency of a Vibrating Body

The frequency of a vibrating body refers to the number of oscillations that occur per unit time. It is an important parameter that determines the pitch of sound and the behavior of waves. The frequency of a vibrating body is affected by different factors, but there are some factors on which it does not depend. One of these factors is the medium in which the body is vibrating.

Medium

The medium in which a vibrating body is located refers to the substance or material that surrounds the body. It can be a solid, liquid, or gas. The medium affects the propagation of waves and the speed at which they travel. However, the frequency of a vibrating body does not depend on the medium in which it is located. This means that if a body is vibrating in air, water, or any other medium, its frequency will remain the same.

Elastic Constants

Elastic constants refer to the physical properties of a material that determine its ability to deform when subjected to external forces. They include parameters such as Young's modulus, shear modulus, and bulk modulus. The elastic constants of a material affect the frequency of a vibrating body since they determine the stiffness of the material. A stiffer material will vibrate at a higher frequency than a less stiff material.

Mode of Vibration

The mode of vibration refers to the pattern of oscillations exhibited by a vibrating body. There are different modes of vibration, including longitudinal, transverse, and torsional modes. The mode of vibration affects the frequency of a vibrating body since each mode has a unique frequency associated with it.

Dimensions

The dimensions of a vibrating body refer to its size and shape. The dimensions affect the frequency of a vibrating body since the wavelength of the wave produced by the body is directly proportional to its size. A larger body will produce a longer wavelength and a lower frequency wave than a smaller body.

Conclusion

In conclusion, the frequency of a vibrating body is affected by different factors, including its elastic constants, mode of vibration, and dimensions. However, it does not depend on the medium in which the body is located. This means that the frequency of a vibrating body will remain the same regardless of whether it is vibrating in air, water, or any other medium.
