Final answer:
The area not visible in your vehicle's mirrors is known as your blind spot. Checking this spot is essential for driver safety, and while virtual images like reflections can't be projected onto a screen, they can be seen and photographed.
Step-by-step explanation:
What you can't see in your rear and side-view mirrors is said to be in your blind spot. The blind spot is an area around the vehicle that cannot be directly observed by the driver while at the controls, under existing circumstances. Side and rear-view mirrors can show most of what is behind and to the side of your vehicle, but they cannot cover every angle. This is why it is crucial for the driver's safety to check their blind spots by looking over their shoulder before making turns or lane changes. However, it's worth noting that modern vehicles often include technologies such as blind spot monitoring systems to assist the driver in detecting vehicles in their blind spots.
Regarding the reflection of light, a virtual image is an image that is formed when outgoing rays from a point on the object always diverge. The virtual image, although it appears to be located at a specific position, cannot be cast onto a screen. Instead, it is an optical effect, such as the image of yourself you see in a flat mirror. In fact, you can see a virtual image and, more interestingly, you can photograph one because the camera lens can focus those reflected rays to create an image of the image.
