An echo can be used to measure distance by sending out a sound pulse and measuring the time it takes for the sound to bounce off the object and return as an echo. The distance can be calculated using the time taken for the sound to travel back and forth and the speed of sound in the medium. By knowing the speed of sound and the time it takes for the sound to return, the distance to the object can be determined.
The process of using sound waves underwater to measure distance is called sonar, which stands for Sound Navigation and Ranging. Sonar systems emit sound waves that bounce off objects in the water and are then detected to determine the distance to the object.
Loudness is the perceived intensity of sound, measured in decibels (dB). Distance affects loudness by causing sound to decrease in intensity the further it travels, as sound waves disperse in all directions. The inverse square law states that the sound pressure level decreases by 6 dB for each doubling of distance from the sound source.
One way to investigate the speed of sound is to measure the time it takes for a sound wave to travel a known distance, like using a stopwatch to measure the time between the sight of a lightning bolt and the sound of thunder. Another method is to use a resonance tube or other equipment to create sound waves and measure the wavelengths at different frequencies to calculate the speed of sound.
There are a few different ways you could measure the speed of sound in water and air. You could record the amount of time it takes a sound to be heard from the source to the destination for example.
One way to measure a wavelength in sound is to calculate it by dividing the speed of sound in air by the frequency of the sound wave. This will give you the distance between two consecutive points on the wave that are in phase with each other.
The oscilloscope will be measuring the wavelength of the sound wave.
time it takes for sound waves to travel to an object and back. By calculating the round-trip time and knowing the speed of sound in water, the distance can be accurately determined.
