The quantity h, now known as the Planck constant, is a universal constant with the approximate value of 6.626 X 10^-34 Js. Max Planck assumed that the radiation energy is emitted in discrete packets called quanta rather than in a continuous way. The energy E of the quantum is related to the frequency Î½ by E = hÎ½.

Headaches Frequent headaches can be another sign that you are anemic. In the context of a blood disorder, however, headaches usually indicate that there is a lack of oxygen reaching the brain. When this happens, the arteries in the head start to swell, causing pain.
If anemia is severe, fainting may occur. Other symptoms include brittle nails, shortness of breath, and chest pains. Blood oxygen levels can be so low that a person with severe anemia can have a heart attack.A physical exam that your doctor does may show: 1  high or low blood pressure. 2  pale skin.3  jaundice.f anemia is severe, fainting may occur.
