D15 Inquiry Activity (continued)Figure 11.25 Step 34. Move the candle to the distance indicated in thefirst row of the table in the “Distance of Candlefrom Mirror” column. Write this actual distanceinto the table in the “Object Distance d o” columnthat is beside it.5. Slowly move the screen along the length of thebench until the image of the candle flame comesinto focus. Measure the distance from the mirrorto the screen. Record this distance as the imagedistance, d iin the table. Record the orientation ofthe flame in the table.6. Very carefully measure the size of the actual flameor bulb and the height of the image of the light.Record these values in your chart.7. Repeat steps 4 to 6 for the next distance indicatedin the table, until all rows of the table arecomplete.Analyzing and Interpreting8. How do you explain the results obtained when theobject was placed at 0.5 of the focal length fromthe mirror?Skill Practice9. Complete the magnification column of the table.Show one of your calculations.Forming Conclusions10. Using the completed table, form a conclusionabout:(a) the magnification of the image based on theobject’s distance from the mirror(b) the orientation of the image based on theobject’s distance from the mirrorRay diagrams model the behaviour of light in mirrors and lenses.431
