Sound
Chapter 6 paragraph 1
Slide 1 - Slide
The speed of sound
The speed of sound is a property.
See page 64 in your book!
Slide 2 - Slide
Calculations with the speed of sound
s= v x t
Slide 3 - Slide
Calculations with the speed of sound
s= v x t
v = velocity (speed) in m/s
t = time in seconds (s)
s = distance in meters (m)
Slide 4 - Slide
Calculations with the speed of sound
s= v x t
v = velocity (speed) in m/s
t = time in seconds (s)
s = distance in meters (m)
v = s / t
t = s / v
Slide 5 - Slide
Klaas sees a concrete pile being driven into the ground in the distance. This is done with the help of small explosions. Klaas hears every little explosion 1.3 s later than he sees it. Calculate the distance between the pile and Klaas.
Slide 6 - Open question
Ron puts his ear on the rails and hears a train coming. The train is 2 kilometers from Ron. Calculate the time it takes for the sound to travel from the train to Ron's ear (through the steel).
Slide 7 - Open question
A fishing boat uses sonar to determine were a lot of fish are. This sonar travels with the speed of sound in salt water. Calculate how deep the fish is in the water if it takes 3 seconds inbetween sending the sound and recieving it.
