Radiometry
The field is called "electromagnetic radiation" or "EMR." It encompasses the study of all types of electromagnetic radiation, including visible light, x-rays, gamma rays, and ultraviolet radiation.
Quartz glass
The violet spectrum is significant in the study of light and color because it has the shortest wavelength and highest frequency among visible colors. This makes it important for understanding the properties of light and how it interacts with different materials. Additionally, the violet spectrum is crucial in the formation of other colors through the process of color mixing.
Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
== == Study of Light & Nature of Light is called " OPTICS "
We use a gamma ray machine to find out where the gamma rays are and where they are pointed to. We also use these machines to study a gamma ray.

A scintillating detector is commonly used in gamma-ray telescopes. These telescopes detect high-energy photons by measuring the light produced when gamma rays interact with scintillating materials. The emitted light is then converted into electrical signals for analysis, allowing astronomers to study cosmic gamma-ray sources. Examples of such telescopes include the Fermi Gamma-ray Space Telescope and the Cherenkov Telescope Array.
The study of changes to materials caused by light is known as photodegradation or photochemistry. This field explores how light can alter the properties and structure of materials over time.
A prism made from a material with high UV transmittance, such as quartz or calcium fluoride, is typically used to study ultraviolet (UV) light. These prisms are designed to efficiently bend and separate UV light into its component wavelengths for analysis.
As far as NASA satellites, both SWIFT and GLAST "study gamma rays", just in different ways
A narrow field of study within a larger field is often called a sub-discipline.
