Question

# The frequencies of two sound sources are $$256\space Hz$$ and $$260\space Hz$$ respectively. The beat frequencies produced by them will be

A
0.025 s1
B
2.5 s1
C
4.00 s1
D
25 s1

Solution

## The correct option is C $$4.00\space s^{-1}$$Given:     $$\nu_1 = 256 Hz$$    and      $$\nu_2 = 260 Hz$$Beat frequencies produced     $$b = |\nu_1 - \nu_2|$$  $$s^{-1}$$   $$b = |256 - 260 |$$  $$s^{-1}$$$$\implies b = 4.00 s^{-1}$$Physics
