Many industrial processes use mirrors and lasers to direct light and laser beams. You use mirrors to drive safely. Warehouses use mirrors on the corners to prevent collisions. Many camera have mirrors in them. We use mirrors for many different applications.

No, mirrors are not needed for all cameras to take photos. The mirror is only used in a reflex camera (a camera where you look through the same lens as the sensor/film). Small point and shoots, rangefinders, and large format view cameras do not use mirrors.

A Digital Single Reflex Lens or DSLR is a type of camera which uses a series of mirrors inside the camera, so that when you look inside the viewfinder of a DSLR, then you will see almost precisely what the camera sensor sees, accurate to a few thousandths of a millimetre. This construction of the mirrors makes the camera more expensive to make, and most cameras simply use the easier and cheaper method, digital viewfinders, which only work when the camera is turned on, whereas on a DSLR, you can look through it anytime (as long as the lens cap is off!)
