1. –/1 points Walker4 26.P.005. My Notes | Sunlight enters a room at an angle of  θ  =  29 °  above the horizontal and reflects from a small mirror lying flat on the floor. The  reflected light forms a spot on a wall that is  d  =  1.6  m behind the mirror, as shown in the figure. If you now place a pencil under the  edge of the mirror nearer the wall, tilting it upward by 5.0°, how much higher on the wall ( Δ y ) is the spot?    cm 2. –/1 points Walker4 26.P.010. My Notes | 10.0 -foot-long, nearsighted python is stretched out perpendicular to a plane mirror, admiring its reflected image. If the greatest  distance to which the snake can see clearly is  26.0  ft, how close must its head be to the mirror for it to see a clear image of its  tail?    ft 3. –/1 points Walker4 26.P.026. My Notes | A small object is located  14.0  cm in front of a concave mirror with a radius of curvature of  40.0  cm. Where will the image be  formed? (Enter a negative value if the image forms behind the mirror.)    cm 4. –/2 points Walker4 26.P.029. My Notes | An object with a height of 42 cm is placed  1.8  m in front of a concave mirror with a focal length of  0.80  m. Find the location and  magnification of the image produced by the mirror, using the mirror and magnification equations. d
