Lasers are used for producing an intense, _ and coherent beam of visible light.
Correct answer: A. Monochromatic
- A. Monochromatic
- B. Bichromatic
- C. Multichromatic
- D. Non chromatic
Explanation
Laser light is monochromatic, directional, and coherent. Lasers are known for producing light that is highly monochromatic, meaning it consists of a single wavelength or color. This is achieved through the process of stimulated emission in the laser medium, resulting in light waves that are all in phase and of the same frequency.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
