Intensity Distribution Curves and Hue, Saturation, and Brightness 4. A certain light has the intensity-distribution curve shown in the figure below. 5. A projector projects a beautiful picture in color on a white screen, which we can assume is perfectly reflective. A photographer wants to use his camera to photograph the beautiful picture Source A Source B from the screen, but there is not enough light. So, he illuminates the screen with bright white light. Describe in words how the hue, saturation, and brightness of the projected picture changes when the floodlight is turned on . Intensity Intensity 400 500 600 700 460 650 Wavelength (nm) Wavelength (nm ) Two figures below show intensity distributions of two light sources, A and B. . For each source, (a) what wavelengths are emitted by the source? (b) describe the color (hue, saturation, and brightness) that would be perceived by a human observer looking at the source . . Suppose that the sources A and B are combined. (c) Sketch the intensity distribution of the combined light . Intensity 400 500 600 700 Wavelength (nm)
