SUMMARY

The discussion centers on calculating the total distance traveled by ultrasound waves emitted by a submarine, which reflects off the sea bed and returns after 0.2 seconds. Given the speed of ultrasound is 1500 m/s, the total distance can be calculated using the formula: distance = speed × time. Since the time includes both the outgoing and returning journey, the total distance is 1500 m/s × 0.2 s = 300 meters.

PREREQUISITES
  • Understanding of the speed-distance-time relationship
  • Knowledge of ultrasound technology and its applications
  • Familiarity with basic physics equations
  • Ability to perform unit conversions and calculations
NEXT STEPS
  • Study the principles of sonar technology used in submarines
  • Learn about the speed of sound in different mediums
  • Explore practical applications of ultrasound in marine navigation
  • Investigate the effects of temperature and pressure on sound speed in water
USEFUL FOR

Students studying physics, marine engineers, and professionals involved in underwater acoustics or sonar technology will benefit from this discussion.

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?
