A beat frequency can be solved with the following equation: Beat Frequency = F1 - F2. In this equation, F1 stands for frequency 1 and F2 stands for frequency 2. You always subtract the smaller frequency from the larger frequency. As a result, you will always result in a positive value as your answer. If you end up with a negative value, then you have switched the place of your frequencies in the equation and you must switch them to be able to result in a positive value. In this problem, you will do 300 - 150, to get an answer of 150. The answer to this problem is 150 Hz.
