Question

While sitting on a dock of the bay, you notice a series of waves going past. You observe that 11 waves go past you in 45 s and that the distance from one crest to the next trough is 3.0 m.

Part A

Find the period of these waves.

Express your answer to two significant figures and include the appropriate units.

Part B

Find the frequency of these waves.

Express your answer to two significant figures and include the appropriate units.

Part C

Find the wavelength of these waves.

Express your answer to two significant figures and include the appropriate units.

Part D

Find the speed of these waves.

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

(a) Time period of 1 Wave ; T=45/11 sec; 4.1 second

(b) Frequency F=1/T = 11/45 = 0.2 Hz

(c) Distance between adjacent crest and trough is /4 ; Here is wavelength

Here /4=3, =12 meter

(d) Speed = frequency x wavelength = 11x12/45 = 2.9 meter/second
