(show your work)</p><p>V = f x λ</p><p>If a water wave oscillates up and down three times each second and the distance between wave crests is 2 m what is its frequency, wavelength, and wave speed? True or False (circle one)</p><p>Waves traveling at the same speed must have the same frequency T F </p><p>Sound underwater travels faster than in air. T F</p><p>Sound waves in space move at the speed of light. T F</p><p>FM radio waves have a smaller wave length than AM radio waves. T F</p><p>A mosquito flaps its wings 600 vibrations per second. What is the frequency of the buzz? ______Assuming sound travels at 340 m / s, how far does the sound travel between wing beats? (wavelength of the sound)</p><p>FM radio waves are measured in megahertz. AM radio waves are measured in kilohertz.</p><p>What is the frequency of your favorite radio station? ______</p><p>Extra credit question:</p><p>The speed of light and radio waves are both 3 x 106 m/s.
