Careers are plentiful for those interested in the scientific realm of the electromagnetic spectrum. Below is a brief description to various fields of study that involve this realm. The links to the left give much more detail on the specific field of study referenced.

• Astronomy is the study of the celestial bodies and their compositions, motions, and origins.
• Astrophysics is the study of the nature and behavior of our Universe, using all the techniques of modern physical sciences.
• Photography is the process of recording pictures by means of capturing light on a light-sensitive medium, such as a film or electronic sensor (CCD).
• Cryptography is the process of taking legible, readable data and transforming it into unreadable data for the purpose of secure transmission, and then using a key to transform it back into readable data when it reaches its destination.
• Radar meteorology is the application of radar to the study of the atmosphere and to the observation and forecasting of weather. Meteorological radars transmit electromagnetic waves at microwave and radio-wave frequencies. Water and ice particles, inhomogeneities in the radio refractive index associated with atmospheric turbulence and humidity variations, insects, and birds scatter radar waves. The backscattered energy received at the radar constitutes the returned signal. Meteorologists use the amplitude, phase, and polarization state of the backscattered energy to deduce the location and intensity of precipitation, the wind speed along the direction of the radar beam, and precipitation type (for example, rain or hail).Much of the understanding of the structure of storms derives from measurements made with networks of Doppler radars.
• Archaeometry is a collective name for an analytical approach to define archaeological cultural remains by means of Natural Sciences to obtain quantitative and qualitative measurements in the domain of seven important fields in Archaeology: identification, prospection, chronometry, provenience, environmentology, biosphere, restoration-conservation. Ultraviolet and X-Ray photography are utilized in this field of study. See the articles, From Archaeology to Archaeometry, and Archaeological Remote Sensing for more information.
