What will happen if you hold a concave mirror in your hand and and direct its reflecting surface towards the sun and direct the light reflected by the mirror on to a sheet of paper held close to the mirror??

Expert Answer:

Dear student
The rays from sun after reflection from the mirror, shall converge at focus. Holding  a sheet of paper at the focus, may cause it to burn if the reflected rays are very strong but if a sheet of paper is held very close to the mirro, it will lie in between the pole and the focus and hence shall only warm up.
Hope this helps.
