What are some applications of the field of spectroscopy?

for identifying elements in a sample

for determining the distance and velocity of galaxies

for producing neon lights

for determining types of chemical bonds

for use in medical imaging devices

Explanation:

Hello,

Field spectroscopy, is a technique used to measure the reflectance properties of  vegetation, soils, rocks, and water bodies in the natural environment, generally under  solar illumination. Some disciplines are interested in the measurement of light reflected  off objects in the natural environment. Natural targets are usually illuminated by the  whole hemisphere of the sky, and thus receive direct solar flux and scattered sky light, thus, it can be applied for determine elements in a sample as each one reflects the light differently, for determining the distance and velocity of galaxies  as one could measure the light velocity, for producing neon lights , for determining types of chemical bonds  as they have measurable energies related with the reflected light and for use in medical imaging devices to determine patrons in the obtained results.
