Questions Related to science & technology

  1. True

  2. False


Correct Option: A
Explanation:

To solve this question, the user needs to understand the concept of sound waves and how they travel through different mediums. The user must know that sound waves require a medium to travel and that the speed of sound can vary depending on the properties of the medium.

Now, let's go through each option and explain why it is right or wrong:

A. True: This option is correct. Sound does travel faster in solids than in liquids, and faster in liquids than in gases. This is because solids have a higher density and more tightly packed particles, which allows sound waves to propagate more quickly. Liquids have a lower density and less tightly packed particles, so sound waves travel at a slower speed compared to solids. Gases, such as air, have the lowest density and most widely spaced particles, resulting in the slowest speed of sound.

B. False: This option is incorrect. Sound does travel faster in solids than in liquids and faster in liquids than in gases. Therefore, the statement that sound travels faster in solids than in liquids, and faster in liquids than in air is true.
