Answer 2

A concave mirror is used as a reflector in a torch light

• A concave mirror is a type of mirror that has a curved surface that is curved inward, like the inside of a bowl. When a beam of light strikes a concave mirror, the light is reflected outward and spread out over a larger area. This makes concave mirrors useful for reflecting light in a wide range of applications, such as in torch lights.

• In a torch light, a concave mirror is used as a reflector to collect and focus the light from the bulb and reflect it forward. The concave mirror has the ability to reflect the light back to a single point, where the light is then directed through a lens to produce a beam of light. This makes the torch light more powerful and efficient, as more of the light from the bulb is directed forward and less is lost to the sides.

• A concave mirror is also used in other applications such as in search lights, car headlights, and stage lighting. In these applications, the concave mirror is used to collect and focus light, producing a powerful beam of light that can be directed at a specific target.
