Question 20 (2 points) Listen In a room painted entirely black, the only illumination comes from three lights shining down on a pure white ceramic tile. The lights produce pure red, blue and green colors on the surface, and are arranged so the light beams overlap as shown below. You are fortunate to have perfect color perception. You look through a red, round, translucent piece of material that is a perfect red filter. You see the original overlapping pattern. You also see a circular area in the middle filtered through the translucent material. Bed Filter BLUE X W Y Z GREEN Identify the perceived colors of the regions W, X, Y, and Z.

They observe the following 0.2 wavelength wave as it hits a barrier with a 0.1 m slit? What shape and wavelengths will the waves have as they pass through the opening? O The waves will continue straight through and the wavelength will be cut in half (0.1 m) The waves will continue straight through and maintain the same wavelength (0.2 m O The waves will bend as they pass through and the wavelength will be cut in half (0.1 m) The waves will bend as they pass through and maintain the same wavelength (0.2 m)Question 23 (2 points) Listen What will happen to this ray of light when it hits this convex lens? O It will reflect toward the center of curveature O It will refract toward the focal point on the opposite side of the lens O It will reflect toward the lens's focal point O It will refract parallel to the principal axis
