Waves and sound review answers. What is the speed of sound at 33 0 C? 5.
Waves and sound review answers A wave has a fundamental frequency of 126 Hz. 16. Now find frequency with the equation v=f*w where v=4 m/s and w=0. Second . What is the speed of a wave with a frequency of 10 hz and a Waves and sounds review answers 1) Water wave properties The diagram on the right represents a water wave reflecting off a barrier. Waves and Sound Review Worksheet 1. (b) The wave fronts are draw at the crest of each wave. If there are 3 waves in a 2-meter long rope, then each wave is 2/3-meter long. Draw the waveform of wave 1 plus wave 2. Second harmonic? d. 8. First overtone? c. How is the speed of sound calculated? Speed of wave = frequency (Hz) X wavelength ( ) (meters) 10. Hint: Subtracting a number is the same as adding the opposite number (i. Are sound waves transverse waves or longitudinal waves? Why? Longitudinal waves because they move back and forth in the same direction as the wave. What type of wave is represented in question #2? Is sound or light representative of this type of wave? longitudinal (compressional); sound 9. When a wave reflects off of a fixed end, what happens to the reflected wave? What if it reflects off of an open end? 3. Longitudinal waves: Waves in which the medium moves back and forth in the same direction as the wave (looks like a slinky). Proper algebra yields 6 Hz as the answer. What is the speed of sound at 33 0 C? 5. (a) What is the angle between the wave fronts and the direction of travel of the wave? 900. b. 9. First harmonic? b. 10. Solve the following problems: a. What is the: a. 667 m. Why can’t you calculate the frequency of the wave in the diagram? Study with Quizlet and memorize flashcards containing terms like What is the source of all waves?, How do frequency and period relate to each other?, What is it that moves from source to receiver in wave motion? and more. e. If there is 12cm between the first and last of the group of four wave Worksheet - Waves and Sound Review a. 5 - 2 = 5 + -2). What is superposition? How does that relate to the interference of waves? 2. What is the range of the frequencies that humans can hear? 4. Draw the waveform of wave 1 minus wave 2. embcsvwnxpoxqwqjvpcvxylgsdqjqkoorkknatvhogriupjaq
