The study and analysis of light according to its component wavelengths is called:

a) Holography
b) Interferometry
c) Colorography
d) Photometry
e) Spectroscopy

1 Answer


  1. The correct answer is e) Spectroscopy.

    Explanation:

    Electromagnetic radiation comes with an array of radiation frequencies. The term Spectroscopy is used when it comes to exploring the electromagnetic spectrum of light. Each wave comes with a different length. Besides, it is able to recreate a variety of colors. A human’s eye can recognize only some of those colors. A visible spectrum includes colors and wavelengths seen by humans. For instance, we are capable of recognizing red color (a 700-635 nm-long wave) or green color (560-520 nm-long wave). On the other hand, we are unable to identify the level of light visibility as well as its dispersion within a prism. Spectroscopy helps to indicate spectrum component wavelength.

    The most notifying achievement in the field of spectrology is the classification of colors by wavelength.
