Question

PHY 221 Prelab: Standing Waves Name 1. Make a sketch of a wave on a string. On the sketch, label the amplitude and wavelength of the wave. V : LA 2. If the frequency of a wave on a string is increased (but the string tension remains constant), what happens to a. Its wavelength? The wavelenath wold DECREASE. b. Its speed? (Note: the material the string is made from does not change) fav The Speed would also INCREASE. Examine the experimental setup shown on page 2 of the lab. If the string tension is increased, what happens to the... 3. The wave speed of the first harmonic? f a. v would ? b. The frequency of the first harmonic? 2 The wavelength of the first harmonic? c. 4. If the wavelength of a wave on a string is increased, will you see more nodes or fewer nodes? Explain.

I would appreciate if you could check my work for #2 and help me out with #3. I tend to get confused with proportions, and I’m not quite sure how to relate tension to frequency and wavelength (unless that is the idea, and one doesn’t affect the other).

Thanks so much!
