The discussion revolves around a problem involving tuning forks and beat frequencies. The original poster presents a scenario where plasticine is added to one fork, affecting its frequency and resulting in a change in the beat frequency observed with another fork. The initial frequency of the unknown fork is questioned, with possible values of 297 Hz or 303 Hz.
Participants are actively seeking clarification on the problem statement and the implications of the beat frequency changes. Some have provided insights into the relationship between the frequencies and the effects of adding plasticine, while others express confusion and request further explanation.
There is a reference to a previous question (#4) that provides context for the frequencies involved, but details of that question were initially missing from the discussion. The problem involves determining the correct frequency of the unknown fork based on the observed beat frequency after modification.
Plasticine (which lowers the pitch) is added to one tine of the tuning forks of unknown frequency referred to in question #4 (initial frequency = 300 Hz possible frequencies 303 Hz or 297 Hz). The number of beats decreases to one(per second). What was the frequency of the unknown fork?
Hi sakonpure6. You're providing the answer, so I'll try to figure out the question ...sakonpure6 said:Well, i know how to calculate the beat difference, but I do not under stand which of the 303Hz or the 297Hz referred to question #4 are the correct initial frequencies before adding the Plasticine! Can some one explain that to me please!
In reality, that second fork must have a frequency of 297Hz or 303Hz, it can't have both fundamentals simultaneously. On the data given for this part of the question, we can't determine which of those two frequencies it does have.sakonpure6 said:Two tuning forks are sounded together, producing three beats per second. if the first fork has a frequency of 300 Hz , what are the possible frequencies for the other fork?
The answers are: 297Hz and 303Hz
