So, in this question, for the solution number, first, we have the beat frequency, beat frequency, which is f.
00:11
So, this f is given by 1 upon t, which is equal to mod of f2 minus f1.
00:17
Now, here basically f is equal to 2.
00:21
So, f2 minus f1 is equal to 2.
00:26
This means f2 is 2 to 0, minus f1 is equal to 2, or we can also say that f1 is equal to 218 or 2 to 2 hz.
00:40
So, basically we cannot say without changing the tension.
00:44
So, this we can't say without changing tension.
01:00
This means then for the question number 1, a correct option is option number c, and this is the required answer for the first one.
01:10
Now, for the second one, in the second one, we have the fbeat, which is equal to mod of f2 minus f1...
