I have a lot of questions to be answered, but i want to understand how i am doing it so if anyone can help me one on one today, i'd appreciate it much. here are a few problems:
(1)the sears building in chicago sways back and forth with a frequency of about 10.0 Hz. what is its period?
(2)an ocean wave has a length of 10.0m. a wave passes a fixed location every 2.0 s. what is the speed of the wave?
(3)water waves in a shallow dish are 6.0cm long. at one point, the water oscillates up and down at a rate of 4.8 oscillations per second.
a.what is the speed of the water waves?
b.what is the period of the water waves?
(4)water waves in a lake travel 4.4m in 1.8s. the period or oscillation is 1.2s.
a. what is the speed of the water waves?
b. what are their wavelength?
(5)the frequency of yellow light is 5.0 * 10 ^14 Hz. Find its wavelength.
(6)the wave speed in a guitar string is 265 m/s. the length of the string is 63 cm. you pluck the center of the string by pulling it up and letting go. pulses move in both directions and are reflected off the ends of the string.
a.how long does it take for the pulse to move to the string end and return to the center?
b.when the pulses return, is the string above or below its resting location?
c.if you plucked the string 15 cm from from one end of the string, where would the two pulses meet?
i have more questions but there's a start
