Question

Wave (m) (m/s)
L 120 600
M 150 600
N 100 600
O 50 600
The table shows information about four waves. Which wave has the lowest frequency?
(1 point)
λ vw
wave L
wave M
wave O
wave N

Answer 1

Wave M.

Since f = v/λ and v = 600 m/s for all, the largest wavelength (150 m for M) gives the smallest frequency: f_M = 600/150 = 4 Hz.
