Lab 3. Wave Motion Variable

Introduction

In this experiment, we determine the relationship between frequency and wavelength using long springs.

Discussion

Question : What is the relationship between frequency and wavelength? Is it linear or non-linear relationship?

Answer : Our seem to have a "Linear relationship." However, the relationship isn't correct its directions. Based on our data, the frequency is increasing as the wavelength is increasing. However, according to the equation,  
the wavelength and frequency has inversely proportion to each other. Therefore, our data did not support the physical property. 

Why? There are third variable that we have while we performed the experiments. We added tension to the spring. When we increase the wavelength, we have not increase the spring's length but just step back by holding a same position on spring. It created increasing of tension by increasing the wavelength. Therefore, our experiment was not accurately designed for examine the relationship between frequency and wavelength.
