Try this first
What is the relationship between the length of a string and the frequency of the stationary wave produced?.
- A.Frequency increases as string length increases
- B.Frequency decreases as string length increases
- C.Frequency remains constant regardless of string length
- D.Frequency is independent of tension in the string
Model answer
What a good answer should say
- Frequency decreases as string length increases
Explanation
Why this works
As the length of the string increases, the frequency of the stationary wave decreases due to the inverse relationship between frequency and wavelength in wave mechanics.
