From your data, what factor(s) affect the speed of a wave? Explain your reasoning. The pitch made by a musical instrument is dependent on the frequency of the wave. Frequency is the inverse of period. What impact do you think the frequency of a wave has on the wave speed? What happens to wave speed as it moves from a medium of low density to one of high density? Explain your response with respect to this lab. When a stringed instrument is out of tune, the player with tighten or loosen the string. If the instrument is initially flat, should they tighten or loosen the string? In the context of this experiment, explain your reasoning.
