Question 513: Waves

Question

Two vibrating tuning forks produce waves given by y1 = 4 sin 500$$\pi $$t and y2 = 2 sin506 $$\pi $$t. Number of beats produced per minute is

Accepted Answer

Y
1
= 4 sin500$$\pi $$t, Y
2
= 2 sin506$$\pi $$t
$${\omega _1} = 500\pi $$, $${\omega _1} = 2\pi \upsilon $$,
$${\upsilon _1} = 250,{\upsilon _2} = 253$$
$$\upsilon  = {\upsilon _2} - {\upsilon _1} = 253 - 250 = 3$$  beats/s
$$ 	herefore $$ Number of beats per minute = 3 ÃÂ 60 = 180
