Answer:

3 Hz

Explanation:

A beat is the pattern of interference among two waves with frequencies which are different.

The difference of the frequencies of the waves gives us the beat frequency.

Here, one frequency is [tex]f_1=440\ Hz[/tex], the other frequency is [tex]f_2=443\ Hz[/tex]

So, the beat frequency

[tex]\Delta f=|f_1-f_2|\\\Rightarrow \Delta f=|440-443|\\\Rightarrow \Delta f=3\ Hz[/tex]

The beat frequency that is produced is 3 Hz
