What is the function of a bulb in a flashlight?
The function of the bulb in a flashlight is to generate some light when some electrical current passes through it. Note: That's actually the whole purpose of the flashlight. If there were no part of it that generated any light, then you do just as well without the flashlight altogether.
How a beam of laser light is different than the beam of light produced by a flashlight?
It does depend on the kind of laser, but the main difference is that a laser emits a focused beam of light of the same wavelength (i.e. color) while a flashlight emits light of many different wavelengths, and 'beams' this light by reflecting it using a concave mirror built into it behind/around the bulb.
What is the purpose of the concave mirror behind the bulb in the flashlight?
You want a torch to emit light in a beam, in only one direction. But the bulb in the torch emits light in all directions, the mirror reflects the light going in the wrong direction(towards the inside of the torch) back out the front of the torch making it brighter. It is concave so as to focus the light more.
Which part of a flashlight is the output?
The bulb is the output. It is what illuminates the dark.
