Question

The "Fourier Transform" of a musical tone is shown at the right. What other term might be used to describe this type of graph? a) wave b) period c) spectrum d) voiceprint e) doppler The photo here captures a moment just before the instant of collapse of the Tacoma Narrows Bridge. The bridge was oscillating with a period of about 3.5 s. It appears that there are 2 anti-nodes in the 2800 ft main span. What is the speed of waves in the bridge? a) 267 ft/s b) 400 ft/s c) 800 ft/s d) 900 ft/s e) 1600 ft/s When a student tunes a guitar string, he turns the tuning screw to increase the tension in the string. Increasing the tension in the string a) decreases the wave velocity and increases the pitch b) increases the wave velocity and decreases the pitch c) decreases the wave velocity and decreases the pitch d) increases the wave velocity and increases the pitch

Explanation / Answer

a) Amplitudes are plotting w.r.t frequency. When we plot such graph insted of its actual wae function, then its called Fourier Spectrum. So, answer is (c) Spectrum
