Anticipated disease is that which may be predicted to occur in individuals with a certain genetic, physical, or environmental predisposition. A communicable disease is that in which the causative organism is transmissible from one person to another either directly or indirectly through a carrier or vector.
All waves are made of traveling energy, and the amount of energy contained in each wave is related in proportion to its frequency. The more energy a wave has, the higher its frequency, and vice versa. When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy. Print | Citation & Date.
So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least. Of visible light, violet has the most energy and red the least. The whole range of frequencies and energies, shown in the accompanying figure, is known as the electromagnetic spectrum. Note that the figure isn't drawn to scale and that visible light occupies only one-thousandth of a percent of the spectrum.
