A surgeon plans to remove a red port-wine stain. What color laser would be appropriate?

Interpretation Introduction

Interpretation:

The color of the laser which would be appropriate in removing the red port-wine stain is to be identified.

Concept Introduction:

Absorption spectroscopy is a technique of measuring the absorption of radiation. The color of any substance depends on the respective colors of the light absorbed and reflected by its molecules or atoms.

Light has both particle and wave properties. Hence, it has dual characteristics.

The wavelength of light determines both its color and energy.

Electromagnetic radiation ranges in wavelengths from the gamma waves to the radio waves region.

In the visible region, white light contains the spectrum of wavelengths ranging from 400 nm780 nm.

Explanation of Solution

The surgeon should use a laser of any color other than red in order to remove the red port-wine stain. This is because red light will be reflected back and not absorbed by the red port-wine stain.

In any substance, when atoms or molecules absorb a certain wavelength of light, they reflect the color which is not absorbed...
