.6m?
____________ m/s
2. What is the wavelength of a water wave given f= .5 hz and v =4m/s?
____________ m
3. A transverse wave f= 10hz travels on a string. The distance between crest and the
adjacent trough is 1.5 m. Find wavelength and the speed.
_____________ m
_____________ m/s
4. A wave machine produces 16 pulses in 4 seconds. Find its period and frequency.
______________ s
______________ hz
5. One pulse is generated every .1s in water. The wavelength is 3.3cm. What speed does
the wave travel?
______________m/s
6. Electromagnetic waves travel through space at 3 E 8m/s. The visible region of light
wavelength ranges from 4 E –7m for violet to 7.6 E-7m for red. What is the frequency
range for light?

9. Two fisherman 24m from shore notice that it takes 6.5 seconds for a wave crest that
passes by them to reach the shore. Their boat also goes through 11 complete
oscillations in 19s. Find the period of the wave and the wavelength.
