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.
Red blood cells are responsible for carrying oxygen to your organs, and hemoglobin is a protein that carries oxygen within the cells, transporting it throughout your body. If you are anemic, your organs are not getting enough oxygen. Symptoms of mild anemia can include: 1  Paleness. 2  Weakness. 3  Fatigue.
