Solution

The correct option is A frequency of 500 Hz is heard with change in intensity take place twice
$c o s (2 π 499 t) + c o s (2 π 501 t) = 2 c o s (2 π 500 t) c o s (2 π t)$
$f_{b e a t} = 2 H z$
Wave pattern of superposition is shown in the figure.
Frequency of 500 Hz is heard with change in intensity take place twice.
