#### The University of NairobiENGLISH 402 1) A wave on a Beaver Dam Lake passes by two docks that are 40

###### Physics

1) A wave on a Beaver Dam Lake passes by two docks that are 40.0m apart.

1. If there is a crest at each dock and another three crests between the two docks, determine the wavelength.
2. If two waves pass one dock every 16secs, determine the period and frequency of the wave.
3. What is the speed of the wave?
1.

a).the wavelength of the wave Sally Sue sent

b) the frequency of the wave produced

c) the speed of the wave

1. 3 nodes produce 3 harmonics, the length of the string is equivalent to three-halves of a wavelength.
2. Wavelength, W = 1.13m Frequency, f = 301 Hz
1. Speed of the wave
2. if you double the frequency of the sound wave, determine the speed.
3. what happens to the wavelength if you cut the frequency in half? How do you know?
