If frequencies are \((v-1)\) and \((v+2)\), then find the value of beats.
- A 2
- B 1
- C 3
- D 4
Answer & Solution
Correct Answer
(C) 3
Step-by-step Solution
Detailed explanation
The beat frequency is defined as the absolute difference between the two given frequencies. Given frequencies are \(f_1 = v - 1\) and \(f_2 = v + 2\). Beat frequency = \(|f_2 - f_1|\) Beat frequency = \(|(v + 2) - (v - 1)|\) Beat frequency = \(|v + 2 - v + 1|\) Beat frequency =…
