A y-t diagram indicates the displacement of a wave over time, showing how the wave changes as time progresses. On the other hand, a y-s diagram indicates the displacement of a wave at a specific point in space, showing how the wave varies at different positions along its path.

A y-t diagram indicates the displacement of a wave as a function of time. It shows how the wave's displacement changes over time, allowing us to analyze the wave's frequency, period, and amplitude. On the other hand, a y-s diagram indicates the displacement of a wave as a function of position. It shows how the wave's displacement varies at a specific point in time, allowing us to analyze the wave's wavelength and wave speed. **

No, r is not a field with the given operations. In order for r to be a field, it must satisfy the field axioms, including closure under addition and multiplication, existence of additive and multiplicative inverses, and distributivity. However, the given operations do not satisfy these axioms, so r cannot be a field with these operations. **
