Vibration - Wave - Light
Some of the learning outcomes of this course are to "describe vibrations, waves, sound, and musical sounds both qualitatively and quantitatively" and to "describe light, light waves, color and image formation both qualitatively and quantitatively." This assignment will specifically address applications of these concepts. Several situations will be described and you will arrange certain situations in a particular order There is a separate worksheet supplied with this assignment where you will write your answers. There...

(1 point) A weight is suspended from the ceiling by a spring. Let d be the distance in centimeters from the ceiling to the weight. When the weight is motionless, d 13cm. If the weight is disturbed, it begins to bob up and down, or oscillate. Then d is a periodic function of t, the time in seconds, so d-0.Consider the graph of d ) below, which represents the distance of the weight from the celling at time 2018/HW 10-Section...
