[SOLVED] Wave problem
a small stone fell into alake causing 40 waves after 4 seconeds, if the radius of the outter circle is 1.6 meters, find the length of the occurred wave and its velocity
well i got two different solutions so far cause i couldn't determine what exactly was meant by (r=1.6m & length of the occurred wave):
1- f = 10 Hz
lambda/4 = 1.6
lambda = 6.4 m
v = lambda.f
= 6.4 × 10
= 64 m/s
========================
2- v = x/t
x = 2pi.r
= 10 m
v = 10/4
= 2.5 m/s (oO)
