Final answer:
The typical wavelength of an argon laser is around 488 nm or 514.5 nm, expressed in nanometers and visible as a green to blue-green color.
Step-by-step explanation:
The wavelength of an argon laser commonly used in various applications is typically around 488 nm or 514.5 nm, with the exact value depending on the specific transitions of the argon atoms that are being utilized. These wavelengths are in the visible spectrum and contribute to the laser's distinct green to blue-green color.
It is essential, however, to note that the provided reference does not give a specific wavelength for the argon laser but rather provides information related to other types of lasers and measurement techniques for wavelengths. To find the exact wavelength for an argon laser, further reference to a source specific to the argon laser's specifications would be required.
