What are the components of a laser?

LED light, battery, and lens
Flash lamp, crystal, and optical resonators
Bulb, wire, and switch
Solar panel, battery, and light emitter

The correct answer is: Flash lamp, crystal, and optical resonators

Laser is an acronym for Light Amplification by Stimulated Emission of Radiation, and it is a device that produces an intense beam of light. The key components of a laser are a medium that can amplify light, a source of energy to cause amplification, and an optical resonator to select and enhance the appropriate light waves. Options A, C, and D do not contain the necessary components for a laser. LED lights, bulbs, and solar panels are not capable of amplifying light, and a battery, wire, or switch do not serve any purpose in a laser's functioning. The correct option B includes a flash lamp as the source of energy, a crystal as the amplifying medium, and the optical resonators to select and enhance the light waves.
