The amplitude of the reflected wave can vary depending on several factors, including the properties of the medium and the nature of the boundary. Here are some general cases:
1. **Amplitude greater than the original wave**: This is generally not possible in a typical reflection scenario due to conservation of energy principles. If the wave is reflecting off a boundary, energy is usually conserved, and the reflecting wave cannot have greater amplitude than the original wave.
2. **Amplitude the same as the original wave**: This can occur under certain ideal conditions, such as when a wave reflects off a perfectly rigid boundary without any energy loss.
3. **Amplitude less than the original wave**: This is often the case. When a wave reflects off a boundary, some energy may be absorbed by the boundary or dissipated, resulting in a reflected wave with a smaller amplitude.
In practice, the most common observation is that the amplitude of the reflected wave is **less than the amplitude of the original wave**, especially in everyday scenarios involving sound or light waves reflecting off surfaces.
