Wave on a string answer key

A pendulum is a small weight on a string or chain. That's it. It can be any weight, and it can be any sort of string or chain. Normally they are small. The weight is normally an object about 1/2 inch by 1 inch in size. The chain or string is usually about 8 inches long. The whole thing fits easily in a small pocket.

Key Points The type of wave that occurs in a string is called a transverse wave. In a transverse wave, the wave direction is perpendicular the the direction that the string oscillates in. The period of a wave is indirectly proportional to the frequency of the wave: T= 1 f T = 1 f.

40. Waves propagate along a stretched string at a speed of 8.0 m/s. The end of the string vibrates up and down once every 1.5 s. What is the wavelength of the waves traveling along the string? 41. A wave on a guitar string has a velocity of 684 m/s. The guitar string is 62.5 cm long. What is the fundamental frequency of the vibrating string? 42.

Plucking the string. The excitation of the string can contain energy at any frequency. We simulate the excitation with white noise: set each of the N displacements to a random real number between -1/2 and +1/2. The resulting vibrations. After the string is plucked, the string vibrates. The pluck causes a displacement which spreads wave-like ...
