Imputed income occurs when: 1  Employees pay less for the coverage than the Internal Revenue Service (IRS) has determined it to be worth, and. 2  The individualâs employer directly or indirectly pays for the coverage over $50,000.
Color is a product of visible light energy. Different colors represent light waves vibrating at different speeds (frequencies). Do you know that most colors of light can be made by mixing together just three colorsâred, blue and green? Light has other properties that make it fun to learn about.
Likewise (and restricting ourselves to optical light for the moment), blue light and red light are both just light, but the blue light has a higher frequency of vibration (or a shorter wavelength) than the red light. The colors of the familiar rainbow of visible light correspond to differing wavelengths of the light, here shown on a nanometer scale.
