Question

Beats are produced by two waves given by $y subscript 1 end subscript equals a sin invisible function application 2000 pi t a n d y subscript 2 end subscript a sin invisible function application 2008 pi t$ . The number of beats heard per second is

Zero
One
Four
Eight

The correct answer is: Four

Number of beats per second= $n subscript 1 end subscript tilde blank n subscript 2 end subscript$
$omega subscript 1 end subscript equals 200 pi equals 2 pi v subscript 1 end subscript$
$⟹ n subscript 1 end subscript equals 1000$
And $omega subscript 2 end subscript equals 2008 pi equals 2 pi n subscript 2 end subscript$
$⟹ n subscript 2 end subscript equals 1004$
Number of beats heard per second
=1004-1000=4
