1) What is the Lens Equation? What do o, i and f stand for in the equation?2) What are the five parts of the Optical Bench used in this experiment? Briefly describe what each part does.3) Describe the procedure for measuring the focal length of a lens.4) What are the most important things to keep in mind in order to get a more accurate measurement of the focal length?5) Extra Credit: The lenses in a telescope perform two jobs: gathering light and magnifying the image. Can a mirror with the same curvature as a lens do the same two jobs? Why?

1) What is the Lens Equation? What do o, i and f stand for in the equation? 
Answer 
o = distance of object 
i = distance of image 
f = focal length of the lens 
1/f = 1/i – 1/o
2) What are the five parts of the Optical Bench used in this experiment? Briefly describe what 
each part does. 
Answer 
Five parts of the lens will be, 
 Object needle 
Object Needle work as an object for the lens on the optical bence. 
 Image Needle 
Image needle is used to determine the location of image on the optical bench. 
 Lens holder 
Lens holder is a stand which helps in holding the lens for the experiment straight and in line 
with the object and image.  
 Lens 
Lens is used to focus light on the focus of the lens with the help of which images are formed.  
 Magnifying glass 
Magnifying glass is necessary in reading the position of vernier and main scale accurately.
