A divergent beam.
The concave and the convection of the lenses.

No they can not. two positives do not make a negative
Mainly, it has to have a large main lens, or main mirror.
An excess of electrons would produce a negative (-) charge since these particles are negative. If you imagine a scale with negative and positive weights, more negative weights would make the scales tip towards the negative end.
It produces only a virtual image in front of the lens.
Concave lens is called a negative lens because it has a negative focal length.
If the lens equation yields a negative image distance, then the image is a virtual image on the same side of the lens as the object. If it yields a negative focal length, then the lens is a diverging lens rather than the converging lens in the illustration.
A magnifying lens
No, convex lens does not produce a real image. It reflects the real image
As you probably have guessed, the term 'DSLR' is an abbreviation. Digital Single Lens Reflex is the full term. In most cameras, there is a mirror inside. That's basically what it means, though I do think this answer requires an edit.
Double lens goggles don't fog up as easily and are more durable than single lens.
An FX lens will produce an image which will fill a full frame sensor or 35mm film. A DX lens will produce a smaller image which will only fill the smaller DX sensor.
Single Lens Reflex Twin Lens Reflex
single lens
All of the light entering the lens converges on the other side to a single point, the lens' focal point.
SLR stands for a single lens reflex camera. Unlike a point and shoot camera, you can change lenses and are able to view your subject through the lens.
