The pigment in the sheet of paper can absorb red, orange, yellow, blue, indigo, and violet. When illuminated with white light, what color(s) of light are reflected and what color the paper will appear to an observer? A. White B. Green C. Red D. Black

Light with a frequency of 5.85×1014 HzHz travels in a block of glass that has an index of refraction of 1.52. What is the wavelength of the light in vacuum ? What is the wavelength of the light in the glass?

Determine the speed, wavelength, and frequency of light from a helium-neon laser as it travels through zircon. The wavelength of the light from the laser is 632.8 nm in air and the index of refraction of zircon is 1.923.   speed =                    m/s wavelength =                nm frequency =                    Hz

Which of the following is TRUE regarding reflection and refraction? a. Reflection can be explained by the particle nature of light while refraction cannot. b.  Refraction can be explained by the wave nature of light while reflection cannot. c. Reflection and refraction can be explained by both the wave and particle nature of light. d. Reflection and refraction can only be explained by the wave nature of light.   The perception of color does not correspond to a unique set of wavelengths. The human eye distinguishes several hundreds of colors and shades. The eye has only three separate types of visual signals. So the different signal perceptions of colors are combinations of these three visual signals. Perception of colors depends upon the relative stimulation of the three color sensitive cells in the retina of the eye. What are the requirements for perceiving colors? a. Eye and light b. Eye, object, and light c. Eye, light, and shadow d. Eye, light, and medium
