Sonic boom is a noise similar to thunder caused by an object moving at supersonic speeds, faster than sound, about 750 mph.
V = lf
f =4.05Hz l = 4.00m
V = lf
v = (4.00m)(4.05Hz)
v = 16.2 m/s
Noah stands 170 meters away from a steep canyon wall. He shouts and hears the echo of his voice one second later. What is the speed of the wave?
Total distance = 170m+170m =340 m
Time = 1 s
v = d/t
v = /
v = 340 m/s
