Study Notes
-
We welcome everyone to the science channel where teachers educate both heart and mind. Today, we are gathering for Sound lecture number TU.
-
We read in the last lecture that sound is a longitudinal wave that requires media to propagate and that the speed of sound varies depending on the medium.
-
One important fact we learned was that when we compare man-made examples, such as water in a jar with 5000 meters per second or air in a container with 1500 meters per second, there is a significant difference between the two.
-
However, we need to consider other factors such as temperature and pressure.
-
For example, if we have a fornace in our midst with a container of air, then when the temperature rises, the container, in response to respect for the air, expands and the temperature controller adjusts accordingly.
-
In Delhi, where I am currently living, there is a temperature controller for temperature and a pressure controller for air pressure.
-
Yesterday, the temperature in Delhi was quite cold and the temperature controller was near 10 degrees Celsius.
-
Despite the cold weather, the temperature controller in Delhi was functioning.
-
We also need to consider temperature and pressure when discussing temperature controllers.

Description
This quiz covers the basic concepts of sound waves, including how sound propagates, the longitudinal nature of sound waves, and the dependence of sound speed on the medium it travels through.
