If two sound waves, `y_1 = 0.3 sin 596 pi [t - x//330]` and `y_2 =0.5 sin 604 pi[t - x//330]` are superposed, what will be the (a) frequency of resultant wave (b) frequency at which the amplitude of resultant waves varies (c ) frequency at which beats aer produced. Find also the ratio of maximum and minimum intensities of beats.

Explanation

To solve the problem step by step, we will analyze the given sound waves and derive the required quantities.

### Given:
1. \( y_1 = 0.3 \sin(596 \pi [t - \frac{x}{330}]) \)
2. \( y_2 = 0.5 \sin(604 \pi [t - \frac{x}{330}]) \)

### Step 1: Identify the frequencies of the waves
The standard form of a wave is given by:
