In which wavelength are lasers typically found?

Visible light
Ultraviolet
Infrared
X-ray

The correct answer is: Infrared

Laser stands for "Light Amplification by Stimulated Emission of Radiation," and it refers to a device that emits light in a narrow, focused beam. While lasers can be found across the entire electromagnetic spectrum, they are most commonly used in the infrared wavelength range. This is because infrared light has a longer wavelength and can be easily focused and controlled, making it ideal for various applications such as communication, medical procedures, and cutting materials. The other options, visible light, ultraviolet, and x-ray wavelengths, are also used in lasers, but they are less commonly found due to their shorter wavelengths and correspondingly more challenging control and focusing requirements. So, while it is possible to find lasers in these wavelengths, they are not as prevalent as those in the infrared range.
