The wave velocity in any medium depends upon:
Correct answer: D. All of the above
- A. Elasticity
- B. Density
- C. Homogeneity
- D. All of the above
Explanation
The correct answer is D, "All of the above" because the wave velocity in any medium depends on all of these factors: elasticity, density, and homogeneity. - Elasticity affects how well a material can transmit mechanical waves. More elastic materials allow for faster wave propagation. - Density plays a role because waves travel at different speeds through materials with different densities. For example, sound waves travel faster in denser materials. - Homogeneity refers to the uniformity of a medium. A more homogeneous medium allows for more consistent wave propagation.

About Wave Speed
Wave speed is the rate at which a disturbance or wave pattern travels through a medium, given by v = fλ, where f is frequency and λ is wavelength. Questions examine how speed changes between media, the relation among frequency, wavelength and period, and why wave speed is not the same as particle vibration speed.
