What is the phase difference between two waves of equal amplitude having same angular frequency with equal wavelength to give.
(i) Maximum amplitude?
(ii) Minimum amplitude?

Explanation

To find the phase difference between two waves of equal amplitude, same angular frequency, and equal wavelength for maximum and minimum amplitudes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Wave Interference:**
- When two waves interfere, they can do so constructively or destructively. Constructive interference occurs when the waves are in phase, leading to a maximum amplitude. Destructive interference occurs when the waves are out of phase, leading to a minimum amplitude.

2. **Maximum Amplitude Condition:**
