The "chemical rays" found by him were afterwards called ultraviolet radiation. [ 7 ] [ 8 ] [ 9 ] Some of Ritter's researches were acknowledged as important scientific contributions, but he also claimed the discovery of many phenomena that were not confirmed by other researchers.
Ultraviolet astronomy is the observation of electromagnetic radiation at ultraviolet wavelengths between approximately 10 and 320 nanometres; shorter wavelengths—higher energy photons—are studied by X-ray astronomy and gamma-ray astronomy. [1] Ultraviolet light is not visible to the human eye. [2]
Using that lesson, they had Argo sweep back and forth across the ocean floor looking for the Titanic's debris trail. [14] They took shifts monitoring the video feed from Argo as it searched the ocean floor two miles below. [citation needed] In the early morning of September 1, 1985, observers noted anomalies on the smooth ocean floor.
New research from the University of California, San Diego could solve a mystery that scientists have puzzled over for several years.
Ozone is transparent to most UV-A, so most of this longer-wavelength UV radiation reaches the surface, and it constitutes most of the UV reaching the Earth. This type of UV radiation is significantly less harmful to DNA, although it may still potentially cause physical damage, premature aging of the skin, indirect genetic damage, and skin cancer.
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight , and constitutes about 10% of the total electromagnetic radiation output from the Sun.
The dull halogen light. The spinning glass plate. The humming that terminates in a “BEEP.” Today the sights, sounds, and smells of the microwave oven are immediately familiar to most Americans.
Scientists have used a food coloring dye used in Doritos and other products to create mice with see-through skin, a low-cost way to assess the body's internal operations.
