Let's go through the questions one by one.

### Question (a):
**Comparing sounds A and B, how would they sound different?**

- **Sound A** has fewer oscillations (waves) in the same amount of time, meaning **lower frequency**.
- **Sound B** has more oscillations, indicating **higher frequency**.
- A **lower frequency** sound (A) would have a **lower pitch**, while the **higher frequency** sound (B) would have a **higher pitch**.

### Question (b):
**Comparing sounds A and C, how would they sound different?**

- **Sound A** has smoother, larger oscillations, meaning **higher amplitude**.
- **Sound C** has smaller, more compressed oscillations, meaning **lower amplitude**.
- A sound with a **higher amplitude** (A) would be **louder**, while a sound with a **lower amplitude** (C) would be **quieter**.

### Question (c):
**Which sound has the highest amplitude?**

- From the waveforms, **Sound A** clearly has the largest oscillation peaks, meaning it has the **highest amplitude**.

### Question (d):
**Which sound has the highest frequency?**

- **Sound C** has the most oscillations in the same time period, meaning it has the **highest frequency**.

### Question (e):
**The speed of sound is 330 m/s. If sound A has a frequency of 220 Hz, what is its wavelength?**

The formula for the wavelength is:
\[
\text{Wavelength} (\lambda) = \frac{\text{Speed of Sound}}{\text{Frequency}}
\]
Substitute the given values:
\[
\lambda = \frac{330 \, \text{m/s}}{220 \, \text{Hz}} = 1.5 \, \text{m}
\]
So, the wavelength of sound A is **1.5 meters**.

### Question (f):
**What is the frequency of sound C?**

Sound C has a higher frequency than sound A. From the waveform, you can see that **Sound C** has about **three times the frequency** of sound A. Since Sound A has a frequency of 220 Hz, Sound C would have approximately:
\[
\text{Frequency of C} = 220 \times 3 = 660 \, \text{Hz}
\]
So, the frequency of sound C is approximately **660 Hz**.
