Question

need help on these O-2 points OntEP4 15 E 07 A string with a length of 0.5 m is fixed at both ends. (a) What is the longest possible wavelangth for the traveling waves that can interfere to form a standing wave on this string? (b) If waves travel with a velocity of 116 m/s on this string, what is the frequency associated with this longest wavelength? Hz 10-11 points GNEP4 15E08 My A string with a length of 0.9 m is fixed at both ends. Suppose that the string is plucked so that there are two nodes along the string in addition to those at either end. wha is the wavelength of the interfering waves for this mode? 1 points OTEP4 15E 09 My N Sound waves have a speed of 340 m/s in room-temperature air. What Hz? s in room temperature air. what is the wavelength of the sound waves for the musical tone is the wavelength of the sound waves for the musical tone concert A, which has a frequency of 440

Explanation / Answer

Here ,

as the rope is tied on both ends,

a) wavelength = 2 * L

wavelength = 2 * 0.5

wavelength = 1 m

the maximum wavelength of the travelling wave is 1 m

b)

speed of wave = 116 m/s

speed = wavelength * frequency

frequency * 1 = 116

frequency = 116 Hz

the frequency of the wave is 116 Hz
