If the two frequencies are nearly equal, find the beat frequency .

1.	If the two frequencies are nearly equal, find the beat frequency .
Answer» SOLUTION :LET ` omega_(1) = 2 PI n_(1) and omega _(2) = 2 pi n_(2) , where n_(1) and n_(2) `are two nearly equal FREQUENCLES. ` :. N_(1) = (omega_(1))/(2pi) and n_(2) = (omega_(2))/(2pi)` So, beat frequency ` = n_(1)~ n_(2) = (omega_(1))/(2pi) ~(omega_(2))/(2pi) = (1)/(2pi) (omega_(1) ~omega_(2))`
