Urgent- Physics coursework on sensing (OCR B)
The coursework is on using sound waves to measure the depth of water in a tank. I emit soundwaves using a sound generator and pick of the reflected wave with a mic. The original wave and the reflected wave are then shown on a osiliscope. I then need to use the speed of sound in air and some how find and combine that with the speed of sound in water? Also I have to measure the different interval time between the reflected wave and original wave?I don't know the speed of sound in water even after research and don't get how to combine them to use S=D/T. I need HELP PLZ!
