No, light that is reflected by a mirror is not emitted by the mirror itself. When light hits a mirror, it undergoes reflection, which means it bounces off the mirror's surface. The mirror does not emit its own light but instead reflects the incident light back into the surrounding space.
The reflection process occurs due to the interaction between the incoming light wave and the atoms or molecules on the mirror's surface. These atoms or molecules absorb the incoming light and re-emit it in a different direction, preserving its properties such as color and intensity. This phenomenon allows us to see objects in a mirror.
It's important to note that the reflected light retains the same characteristics as the incident light, apart from a change in direction.
