Other Drugs. Drugs used for treating epilepsy, such as phenytoin and carbamazepine, can reduce thyroid levels. Certain antidepressants may cause hypothyroidism, although this is rare. Interferons and interleukins are used for treating hepatitis, multiple sclerosis, and other conditions.
Visible light has frequencies ranging from 4*10 14 Hz to 8*10 14 Hz (400 THz to 800 THz) and wavelengths from 3.8*10 -7 m to 7.5*10 -7 m (380 nm to 750 nm). Red light has the lowest frequency (longest wavelength) and violet light has the highest frequency (shortest wavelength) of visible light.
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.
