Written Laser Hair Removal Practice Exam

How does IPL differ from lasers in emitting light?

1. IPL emits only one wavelength

2. Lasers emit a range of wavelengths

3. IPL emits every wavelength between 400-1200 nm

4. Lasers are color blind

The correct answer is: IPL emits every wavelength between 400-1200 nm

IPL and lasers are two different technologies used for light-based treatments such as hair removal. The main difference between the two is the type of light they emit. While IPL emits a broad range of wavelengths, typically from 400-1200 nm, lasers emit only one specific wavelength. This is because lasers use a single medium to produce a narrow, intense beam of light, while IPL uses a flash lamp that produces a range of wavelengths. Therefore, option C is the correct answer as it accurately reflects how IPL and lasers differ in their emission of light. The other options are incorrect because they do not accurately describe the difference between IPL and lasers. Option A is incorrect because IPL does not emit only one wavelength, unlike lasers. Option B is also incorrect because lasers do not emit a range of wavelengths. Option D is incorrect because lasers are not color blind, they emit specific wavelengths of light.
