most infrared wavelengths are absorbed by Earth's atmosphere
There is not many remains of the Precambrian time
Deep-sea organisms have been difficult to study because the ocean floor is hard to get to.
Because it is terrestrial and it had been formed 300 billion years ago.
The Precambrian interval of earth history is difficult to study because of its tremendous age. Many of the original rocks have been destroyed by weathering and erosion, or have been greatly altered by heat & pressure during burial, a process known as metamorphism.
no fossils of organisms with hard parts. the few soft body part fossils found rarely fossilize well.
most infared wavelengths are absorbed by earths atmosphere... :)
a study of gynoclogist is difficult

you should study waves with a higher frequency and shorter wavelengths
The primary goals of Webb are to study galaxy, star and planet formation in the Universe. To see the very first stars and galaxies form in the early Universe, we have to look deep into space to look back in time (because it takes light time to travel from there to here, the farther out we look, the further we look back in time). The Universe is expanding, and therefore the farther we look, the faster objects are moving away from us, redshifting the light. Redshift means that light that is emitted as ultraviolet or visible light is shifted more and more to redder wavelengths, into the near- and mid-infrared part of the light spectrum for very high redshifts. Therefore, to study the earliest star formation in the Universe, we have to observe infrared light and use a telescope and instruments optimized for this light. Star and planet formation in the local Universe takes place in the centers of dense, dusty clouds, obscured from our eyes at normal visible wavelengths. Near-infrared light, with its longer wavelength, is less hindered by the small dust particles, allowing near-infrared light to escape from the dust clouds. By observing the emitted near-infrared light we can penetrate the dust and see the processes leading to star and planet formation. Objects of about Earth's temperature emit most of their radiation at mid-infrared wavelengths. These temperatures are also found in dusty regions forming stars and planets, so with mid-infrared radiation we can see the glow of the star and planet formation taking place. An infrared-optimized telescope allows us to penetrate dust clouds to see the birthplaces of stars and planets. (Also, at one of the other commenters, Webb is not Hubble's replacement, but rather a successor.)
Seismographs,Thermal Imagers,Infrared Cameras, And Etc.
Both are involved in the study of the optical spectrum after breaking it down into component wavelengths.
There is no term as there is no reason to study them.
they use radio telescopes, infrared, gamma ray, and etc.

Mass Communication study is so difficult study so i not want to study this
