1. The process of transmitting and receiving of signal as an application property of sound under reflection. It is also known as SONAR.
2. Media where sound travels the slowest
3.There is a_______value increase in the velocity of sound every 1°C increase in temperature.
4. Sound starts with_____between two objects.
5.An animal that uses the principle of reflection of sound in order to navigate its surrounding.
Answer:
1. The process of transmitting and receiving signals as an application property of sound under reflection is called echolocation. It is also known as SONAR (Sound Navigation And Ranging).
2. The medium where sound travels the slowest is gas, specifically air. This is because the molecules in gas are more spread out compared to solids and liquids, making it harder for sound waves to propagate.
3. There is a 0.6 m/s value increase in the velocity of sound every 1°C increase in temperature. This means that as the temperature increases, the speed of sound also increases, since the molecules in the medium vibrate faster.
4. Sound starts with vibrations between two objects. When an object vibrates, it creates a disturbance in the surrounding medium, such as air molecules, which then propagate as sound waves.
5. An animal that uses the principle of reflection of sound in order to navigate its surrounding is a bat. Bats emit high-pitched sounds, which bounce off objects and return as echoes. By analyzing the echoes, bats can determine the location, distance, and shape of objects in their environment, allowing them to navigate and hunt accurately even in complete darkness.
