Who discovered the ultraviolet ray?
Johnna Wilhelm Ritter discovered the ultraviolet ray
What did Wilhelm Von roentgen do?
In 1895, Wilhelm Rontgen discovered rays that he named x-rays. This discovery came while he was studying electric currents as they passed through gas that had very low pressure.
How did Thomson got to his discovery?
J.J. Thomson discovered the electron in 1897 while experimenting with cathode rays in a vacuum tube. By applying electric and magnetic fields, he observed that the rays were deflected, indicating they were composed of negatively charged particles. His measurements showed that these particles were much smaller than atoms, leading to the conclusion that they were fundamental components of matter. This groundbreaking work fundamentally changed the understanding of atomic structure.
Why did Wilhelm roentgen name his discovery xray?
Wilhelm Röntgen named his discovery "X-ray" to denote the unknown nature of the rays he had discovered. The "X" symbolically represents an unknown variable in mathematics, reflecting his uncertainty about the nature of the radiation. Röntgen's use of this term helped emphasize the mysterious aspect of the rays, which were later understood to be a form of electromagnetic radiation. This naming convention has persisted in the scientific community to this day.
What did Joseph john Thomson contribute in the history of atom?
he discovered that electrons and protons are inside an atom... which means that an atom is not the smallest.WRONG! - Though only the striked bold italics are.Thomson only discovered the electron. After initially researching cathode rays, he dabbled a bit, but was only re-interested in it about year later, because of another scientist's trial. This "other" scientist - using a collector - found that cathode rays had negative charges. Thomson, his cathode ray curiosity renewed, decided to experiment more. His experiment was also coincidentally with cathode rays and collectors. However, his specific experiment was used to discern the mass difference of the collector after firing cathode rays at it; this is what makes him important in history. He fully showed the existence of the electron (a formerly non-existant, smaller than an atom, subparticle) and formed a model based on it - famously known as the plum pudding model.- A.L
Who invented ultraviolet rays?
Johann Wilhelm Ritter discovered ultraviolet rays i 1801. He discovered it when observing that sodium chloride becomes oxidized when exposed to certain types of light.
When did people start knowing about uv rays?
Ultraviolet light was discovered by Johann Wilhelm Ritter in 1801.
What animal see ultraviolet rays?
Bees can see ultraviolet rays.
Who discovered ultraviolet waves?
Ultraviolet waves were discovered by the German physicist Johann Wilhelm Ritter in 1801 during his experiments with silver chloride. He found that invisible rays beyond the violet end of the spectrum had a photographic effect on silver chloride, leading to the discovery of ultraviolet light.
Are X-rays and Gamma rays higher frequencies than ultraviolet rays?
Yes, X-rays and gamma rays have higher frequencies than ultraviolet rays.
Do both x rays and gamma rays have higher frequencies than ultraviolet rays?
Both Gamma Rays and X Rays have a much high frequency that Ultraviolet Rays.
What wavelengths just a little higher than ultraviolet rays are called?
The next name of wavelengths longer than ultraviolet rays is "violet light".
Ultraviolet rays are visible or not?
Ultraviolet rays cannot be seen or felt. Ever had a sun-burn? I say UV rays can be felt.
Infrared rays have a shorter wavelength than ultraviolet rays?
This statement is incorrect. Infrared rays have a longer wavelength than ultraviolet rays. Infrared rays have wavelengths longer than visible light, while ultraviolet rays have wavelengths shorter than visible light.
In 1913 french scientist Charles Fabry discovered this layer in Earths atmosphere that protects Earth from ultraviolet rays?
charles fabry discovered the ozone layer 1913 the ozone layer
How do you use the words ultraviolet rays in a sentence?
Too much exposure to the ultraviolet rays from the Sun can prove to be fatal.
What is another name for ultraviolet rays?
