Darkness_hacker99 SG Lets say I am standing at a point, from a cliff, 1 side 330m 1 side 660m, and assume the sound is traveling at the speed of 330m per Sec, how long is the time difference between 1st and 2nd echo? edit:typo
Agenda SG taking this diagram if there is no direction specified.. i would assume that the echo travels both sides, then the time you will hear echo is 660m = 4 sec 330m = 2 sec
Darkness_hacker99 SG Thanks! This is what I thought too! So the difference will be 4 sec minus 2 sec = 2 sec.
Darkness_hacker99 SG Because we need to know the speed of sound and distance to find out the time(in seconds) echo is heard.
AndrewPKYap SG are you sure the phrase " the "speed of sound travel at"?" is meaningful? How does "speed of ANYTHING TRAVELS"? Things move (travel) but how does the speed of SOMETHING travels?
HyuugaNeji SG the speed of lorry is 50km/h the speed of lorry travels at 50km/h (this part is wrong) ya 4-2=2
