Absolutely with the right kind of mirror.
The mirror needs to be concave. Kind of the opposite of those safety mirrors that we use on cars and to see around corners. (Those are convex.)
Check this link out... it shows how make a polished convex mirror out of the bottom of a soda can using milk chocolate (I kid you not) as the polishing agent. Then use can use the can to light a fire using a small piece of dry wood.

No, you need a magnifying glass. Reflection from a mirror is not a good heat transfer and reflection from a high energy object is not enough to set a fire. The reflection is not a direct heating source.

The Babylonians used mirrors to burn Roman war ships approaching the cost. The philosophy is indeed the same of a magnifying glass but then on a great scale.

very well, now you couldnt absolutely bypass right into a room lined with mirrors and shine a laser and anticipate the entire room to replenish, for most motives (youre contained in the way of a minimum of one million different instructions the mild might want to ought to holiday). yet when there have been a splendidly round room lined with a splendidly reflective reflect, interior which there change right into a perfect vacuum and also you by some ability were given a beam of sunshine to "commence" in there without a source to intrude with the reflections, theoretically it is going to bop round continuously, yet that brings up the cat contained in the field theory of quantum mechanics, technically, it's going to be bouncing round and under no circumstances bouncing round mutually till you absolutely word it so that you may want to under no circumstances quite understand

If you get a lot of mirrors and point them at one point then maybe. Or if the mirror is parabolic shaped you can. That's how they make solar ovens.

If the obtuse angle is counteracted by the oblique lie you can.

No. You need a magnifying glass.

No I can't.. On the other hand I don't believe anyone could.
