Pressing the finger at different places changes the length of string, which changes the wavelength of standing wave , affecting the frequency. Think of it like a guitar string, being tuned up to pitch: if you increase the string tension, the string's natural frequency will increase but since the string's length did not change, the wavelength of the string's natural frequency will remain the same. The explanation I've found in my studies goes something like this: If you imagine a wave moving through a string, the molecules of the medium are displaced as it passes through. (Smaller lengths of string result in shorter wavelength and thus higher frequency.) This means that the vertical position of the wave depends on both the time and the horizontal position, and our (more general) wave equation now becomes y(x ,t)=Asin(kx−ωt+φ) (The negative sign on the time term is there to make the overall phase of the wave comeout correctly) 8. Explain the shape of the curve of your plot of wavelength as a function of the square root of the tension. The experiment is basically concerned with the effect that the tension.

Note that this statement is only true for the harmonics of standing (stationary) waves. How does tension affect the speed of a wave in a rope? Specifically, as the frequency goes down, the speed goes down by the same factor, and so the wavelength doesn't change. The wavelength, frequency and speed are determined. Imagine, for instance, a guitar. Increasing the tension on a string increases the speed of a wave , which increases the frequency (for a given length). maine road stadium postcode . Increasing the tension on a string increases the speed of a wave, which increases the frequency (for a given length). I would suggest reviewing hyperphysics! What does increasing the tension do to the waves' velocity? When waves travel across strings, the larger the tension of the string the faster the velocity of the wave. The resonant frequency of a string can be increased by: * Shortening the length. Set to "Oscillate" and "No End" Keep the ruler and timer on . Standing waves are produced at different frequencies, and the frequency of a standing wave is proportional to the square root of the tension in the string. Wavelength v Frequency<br />f = v/λ<br />The relationship between wavelength and frequency is inverse.<br />In an inverse relationship, decreasing one variable (such as wavelength)increases the other (in this case, frequency)<br /> 11. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l . 416. Does tension affect wavelength? #2. what factors affect the speed of a wave?
