What effect on the bilirubin molecule does ultraviolet light have?
Ultraviolet light helps convert unconjugated bilirubin into its water-soluble form, called photoisomerized bilirubin. This process, known as phototherapy, helps the liver excrete bilirubin more easily, reducing the risk of jaundice in newborns.
Does ultraviolet light stabilize the bilirubin molecule?
No, ultraviolet light does not stabilize the bilirubin molecule. In fact, exposure to ultraviolet light can break down bilirubin and decrease its levels in the body, which can be beneficial in certain medical conditions like jaundice.
Why is the photoelectric effect more effective with violet light than with red light?
Violet light has a higher frequency and shorter wavelength compared to red light, which means each violet photon carries more energy. This higher energy of violet light photons allows them to more easily overcome the work function of the material and eject electrons, making the photoelectric effect more effective with violet light than with red light.
How will violet light react in the process of dispersion?
Violet light will refract when passing through a prism due to its shorter wavelength causing it to bend more than longer wavelengths like red light. This dispersion separates the violet light into its constituent colors creating a rainbow effect.
Why does violet light eject electrons from a certain photosensitive surface whereas red light has no effect on that surface?
Violet light has higher energy photons compared to red light. This higher energy allows violet light photons to transfer enough energy to electrons in the photosensitive surface to eject them, a process known as the photoelectric effect. Red light photons do not have enough energy to overcome the work function of the surface and therefore cannot eject electrons.

Which blood chemical is light sensitive?
The blood chemical constituant that is light sensitive is Bilirubin..
What color tube bilirubin?
The tube used for bilirubin testing is typically a brown or amber-colored tube. This color is chosen to help protect the sample from light exposure, as bilirubin is light-sensitive.

Which color of invisible light has the shortest wavelength?
Violet light has the shortest wavelength of the visible spectrum.
What colours of light are absorbed by violet?
Violet light (400-450 nm) absorbs yellow and orange wavelengths. This is why violet objects appear to be violet because they reflect violet light and absorb others.
What molecule is used to capture light energy?
Chlorophyll captures light energy using photosynthesis. Energy is absorbed through wavelengths. It can absorb violet-blue and orange-red light energy easily.
What type of preparation does bilirubin specimens require?
Protection from light.
Why sky appear blue not violet?
The earth's atmosphere scatters sunlight in all directions, which is why the sky appears blue to our eyes. This scattering effect is stronger for shorter wavelengths of light, such as blue and violet, but blue light is scattered more efficiently than violet light due to its longer wavelength, resulting in the sky appearing blue.
