Use your knowledge of and experience with waves and to answer the following and show your work.   What is the frequency in Hertz (Hz) of a signal that repeats 80,000 times in a minute?     What is the period of the wave in part (a)?       Now suppose you have a composite signal (composed of many frequencies). If the frequencies range from 50 Hz to 600 Hz, what is the (analog) bandwidth?

Calculate the length of a closed pipe resonator whose first harmonic is 250Hz. Assume that velocity of sound is 343m/s.

From the snapshot given on the top, draw a history graph D(x=2cm,t). I found the graph but I'm not sure exactly how that answer was found.

Please, do not forget to SHOW ALL YOUR WORK and Calculations and Also explain your answers. Remember The DUE DATE. This Assignment represents 50% of this module's grade. Total: 8 questions. Please, use a PDF or MS Word DOC format to submit your work. Questions: 1. All the waves shown have the same speed in the same medium. Use a ruler (or eyeball if you can) and rank these waves from most to least for: (a) amplitude, (b) wavelength, (c) frequency, and (d) period ?     2. What is the period, in seconds, that corresponds to each of the following frequencies: (a) 10 Hz, (b) 0.2 Hz, (c) 60 Hz? 3. A skipper on a boat notices wave crests passing his anchor chain every 5 s. He estimates the distance between wave crests to be 15 m. He also correctly estimates the speed of the waves. What is this speed? 4. A weight suspended from a spring is seen to bob up and down over a distance of 20 cm twice each second. What is its frequency? Its period? Its amplitude? 5. Radio waves travel at the speed of…

Choose the steps below in the appropriate order to explain why the sky is blue. Light that is primarily blue comes from all directions in the sky. White light with all colors is emitted by the sun. 9When interacting with molecules, blue light with shorter wavelength scatters more in all directions. e White light interacts with molecules in the atmosphere. Submit Answer Tries 0/2 Choose the steps below in the appropriate order to explain why sunsets can appear red. When interacting with molecules, red light with longer wavelength scatters less. White light with all colors is emitted by the sun. White light interacts with molecules in the atmosphere. 0Light that is primarily red continues along the path from the sun to your eyes.

Student 1: The red light has a higher wavelength (A) than the blue light. Using the equation v = f* A, that shows that the red light has a larger velocity (v) as well. Student 2: But both kinds of light should be moving at the same speed, since they are both going through the same medium, space. I think the blue light needs to have a higher frequency than the red light, to make up for the red light's higher wavelength. Do you agree or disagree with either or both of the students? Explain your reasoning.

Standing Waves in Air Columns, fixed length- WT-1 You are designing an air-filled tube that is closed at one end and open at the other to have a sound wave with a fundamental frequency of 512HZ in air at sea level. a) Sketch a figure like the one shown to the right and draw below the tube the fundamental mode of vibration and the next three harmonics. Beside each pattern, write the tube-length-to-wavelength relationship. b) Find the length needed for this tube. c) Find the frequency needed for each standing wave pattem you sketched. Use your results from above to find the frequencies; do not use equations from memory. open closed

Using the diagram, a. Compare (and contrast) how line A and line B are formed. b. On the diagram, draw in all the lines of constructive and destructive interference, and label all of the lines with their path length difference (ΔL) in terms of the wavelength (λ).
