12. A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingers. This is often done as a physics demonstration, creating a high-pitched, very annoying whine. From a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tube. In particular, both ends of the rod are anti-nodes. What is the fundamental frequency of a 2.50 m -long aluminum rod? The speed of sound in...
,50, the standing wave shown in Figure 7-30 is set up on a string, The string has length of s t and At time locity 50 ft/s. What are the frequencies of the first eight allowed normal modes on this string- a)25,50, 75, , . . , 17.5, 20.0 Hz b) 2.5,75, 12.5,... ,32.5, 375 Hz c) 5, 10, 15,,35, 40 Hz d) 5, 15, 25, .,65, 75 Hz e) 10, 20, 30, .,80 Hz lex wave shown at t-0...
please answer all pre-lab questions 1 through 5. THANK YOU!!! this is the manual to give you some background. the pre-lab questions.. the pre-lab sheet. Lab Manual Lab 10: String Waves & Resonance Before the lab, read the theory in Sections 1-3 and answer questions on Pre-lab Submit your Pre-lab at the beginning of the lab. During the lab, read Section 4 and follow the procedure to do the experiment. You will record data sets, perform analyses, answer questions, and...
I need help with the 3,5,7 harmonics part of the question Resonance Pre-Lab Assignment (1 point) Recall from the "Introduction to Waves" lab that it was easy to calculate the harmonic number (n) and wavelength (A) of standing waves on a string by counting the number of antinodes (n -21/n). That was a system with nodes fixed at the end points. Today you will be working with a system that has one open end and one closed end (i.e. a...
Can someone help me do my prelab please. Thank you. Resonance Pre-Lab Assignment (1 point) Recall from the "Introduction to Waves" lab that it was easy to calculate the harmonic number (n) and wavelength ) of standing waves on a string by counting the number of antinodes 2L/n). That was a system with nodes fixed at the end points. Today you will be working with a system that has one open end and one closed end (i.e. a node fixed...
Question 4 to 11 plz Dr? Standing Waves on a String Physics Topics If necessary, review the following topics and relevant textbook sections from Serway / Jewett "Physics for Scientists and Engineers", 9th Ed. • Mathematics of Traveling Waves (Serway 17.2) • Speed of Waves on a String (Serway 17.3) • Superposition of Waves (Serway 18.1) • Standing Waves on a string (Serway 18.2, 18.3) Introduction Imagine two sinusoidal traveling waves with equal amplitudes and frequencies moving in opposite directions....
