Homework Statement
When you drop a rock into a well, you hear the splash 1.5 sec later. How deep is the well?
Homework Equations
The Attempt at a Solution
Speed of sound 343m/s
x=(343m/s)(1.5)=514.5
newfie88 said:do i need to take half of the time...Also is the answer 11 m.
newfie88 said:Im sorry i don't really get this whole physics thing...does gravity have anything to do with this question...and the answer in back of the book is 11 m but no matter what i do icant seem to get that answer
When a rock is dropped into a well, it creates a disturbance in the water which causes sound waves to travel through the water and to the surface of the well.
Sound waves travel through water in a similar way to how they travel through air, by creating vibrations. However, sound waves actually travel faster and farther in water due to its higher density compared to air.
The sound of a rock dropping into a well becomes fainter as it travels through water because water is a denser medium than air. As sound waves move through the denser medium, they lose energy and become quieter.
Yes, sound waves can travel through all types of materials, including solids, liquids, and gases. However, the speed and distance that sound travels can vary depending on the density and properties of the material.
When sound waves reach the surface of the well, they are reflected back into the water and can continue to travel through the water until they reach the edges of the well or are absorbed by the well walls. This is known as an echo and is commonly heard when a sound is made in a confined space, such as a well.
