Which of the following properties describe laser light?

Incoherent and polychromatic
Coherent, monochromatic, and collimated
Scattered and Non-collimated
Diffuse and multicolored

The correct answer is: Coherent, monochromatic, and collimated

Laser light has specific properties that make it different from regular light. First, it is coherent, meaning that the waves of light are all in phase with one another. This results in a very focused and concentrated beam. It is also monochromatic, meaning that it consists of a single, specific wavelength of light. This is what gives laser light its intense color. Lastly, it is collimated which means that the beam is parallel and has little to no divergence. Option A is incorrect because laser light is not incoherent or scattered, and it is only one color or monochromatic. Option C is incorrect because laser light is not scattered or non-collimated, it is actually collimated. Option D is incorrect because laser light is not diffuse and it is not multicolored, it is actually very focused and only one color or monochromatic.
