Thin Lenses

A diverging lens ray diagram and thin lenses calculation  

This problem focuses on identifying lens type, sketching ray diagram, identifying image type, predicting the magnification, calculating image location using thin lenses equation, and calculating magnification. 

An owl is sitting, as shown, in front of a diverging lens with the pictured focal points. 

  1. Using the provided optical axis (or a good copy), carefully and precisely draw a ray diagram to find the location of Owl’s image. Use a straight edge! Indicate where the image appears. 

  2. Is the image real or virtual? Explain how you determined this. 

  3. Estimate the magnification of the image. 

  4. The owl is sitting 80 cm from the lens, which has a focal length of 50 cm. Using the math representation, find the location of the image. 

  5. Using the math representation, find the magnification of his image.
