We will give you further guidance as needed to help you solve this problem, but you need to show us that you are trying to solve it and not just asking us to do your homework for you.You have not shown any work on the solution. Please try to work on the solution and post your attempts here. We will be happy to help you understand and solve the problem, but we cannot do your homework for you. Show us what you have tried and where you are stuck, and we can guide you from there.

A submarine sends out a pulse of ultrasound to check how close it is to the sea bed. The reflected waves are detected 0.2 seconds later. Work out the total distance traveled by these detected waves. The speed of ultrasound is 1500m/s .

[New user reminded to post schoolwork in the Homework section and show their work on the solution]

Welcome to the PF. :smile:

We can only help you if you show your best efforts to work on the solution. What are the Relevant Equations (involving speed, distance and time)? Can you show how to work with the Relevant Equations to start to figure out this problem?
 

FAQ: How Far Does Ultrasound Travel in 0.2 Seconds?

How does sonar echolocation work?

Sonar echolocation works by emitting high-frequency sound waves into the environment. These sound waves bounce off of objects and return to the source as echoes. The time it takes for the echo to return is used to calculate the distance to the object. This process is similar to how bats use echolocation to navigate.

What is the purpose of using sonar echolocation?

Sonar echolocation is primarily used for navigation and detection of objects underwater. It is commonly used by marine animals such as dolphins and whales to locate prey and navigate through their environment. It is also used by humans for various purposes such as mapping the ocean floor and detecting underwater objects.

How is sonar echolocation different from regular sound?

Sonar echolocation uses sound waves with much higher frequencies than regular sound. These high-frequency waves are able to travel longer distances and provide more detailed information about objects in the environment. Additionally, sonar echolocation uses the time it takes for echoes to return, rather than the intensity of the sound, to gather information about objects.

What are some real-world applications of sonar echolocation?

Sonar echolocation has a wide range of applications in various industries. It is commonly used in military and defense operations for detecting and tracking submarines. It is also used in the fishing industry to locate schools of fish and in the oil and gas industry for underwater pipeline inspection. Additionally, sonar echolocation is used in medical imaging to create images of internal body structures.

Are there any potential negative impacts of sonar echolocation?

There have been concerns about the potential negative impacts of sonar echolocation on marine animals. The high-frequency sound waves can disrupt their natural behavior and cause hearing damage. There have also been cases of marine animals becoming stranded after being exposed to intense sonar signals. As a result, regulations have been put in place to limit the use of sonar in certain areas and at certain times to protect marine life.
