I did a lab about Standing waves on a string and it asked me the following qeuestions:
Discuss any errors arising from the method used to establish the standing wave pattern.
- I think air resistance, linear density of string is non uniform, tension of the string is not constant, and the frequency of the vibration not being constant may have played a part in the standing wave patterns... I can't really think of anything else and I'm not sure how exactly these errors can affect the standing wave.
How might the tension in the string not equal the weight of the hanging mass?
I have no idea how to answer this question, I know that tension is equal to the weight only if the acceleration is zero.
What happens when the vibrator is at an angle of 45 to the wire?
Does it affect the frequency?

I need to see a diagram of the setup, or a description. Was the string horizontal or vertical? where was the weight, how was it connected? What type of vibrator was used? How was it connected to the string?
The string is horizontal, the mass is on the right side attached to a pulley. I'm not sure which kind of vibrator was used.
