White light is made up of all colors. The rainbow is actually the decomposition of white light by droplets of water like a prism.
Each color corresponds to an electromagnetic radiation of particular frequency and wavelength.
The sensitivity of the eye is maximum around 550 nm, in the yellow-green. The spectrum of visible light ranges from 400 to 780 nm but its perception depends on each individual (tastes and colors ...).
The colors that are visible to our human eyes are given by a certain spectrum of light defined by a range of wavelengths of energy. A typical human eye can see a spectrum of wavelengths of energy that are from about 380 to 740 nanometers. The colors of the visible light range from violet (380–450 nm) to red (625–740 nm).
The best way for the nurse to help alleviate the back pain to a woman whose fetus in the occiput posterior position which is experiencing increase pain is to apply counter pressure to the back. These counter pressure help the woman to cope back labor associated with occiput posterior position
There should be 22% Thymine because of Thymine pairs with Adenine, which on the table is shown to be 22%. (the complementary base pair are always equal). and the same would apply to Guanine (28%) and cytosine (28%).
