Written Laser Hair Removal Practice Exam

Lasers emit a single, specific wavelength of light, while IPL (intense pulsed light) emits a broad spectrum of wavelengths. This makes IPL a more versatile option for certain treatments, while lasers can be more precise and effective for specific purposes. Options A and C are incorrect because they suggest that lasers don't emit a single wavelength, which is incorrect. Option D is incorrect because lasers can emit wavelengths that are not visible to the human eye.
