Final answer:
The area not visible within your mirrors when driving is called the blind spot, which requires physical checking to ensure safety. In optics, the virtual image from a mirror can be photographed, as it is the projection of light rays.
Step-by-step explanation:
The area you cannot see within your inside and outside mirrors is called the blind spot. This occurs because the mirrors cannot reflect the light from all angles of objects behind or beside the vehicle due to their positioning. To check your blind spot, physical head movement to look over your shoulder is required to ensure that the way is clear. This is crucial for safe driving practices, particularly before changing lanes.
An example to illustrate the concept of a blind spot in physics can be seen in the way light reflects off mirrors and lenses. In optics, when light from an object reflects off a mirror or passes through a lens, it can create a virtual image. The human eye can see this virtual image because light seems to be coming from a point behind the mirror or lens, even though it actually converges in front of it. Hence, the virtual image can be seen and, in fact, can be photographed because it is essentially a projection of light rays.
