5.4Understanding lenses
Explain focal point andfocal length.
Determine the focal pointand focal length of aconvex lens.
Determine the focal
point and focal length ofa concave lens. Draw ray diagrams to
show the positions andcharacteristics of theimages formed by aconvex lens.
Draw ray diagrams toshow the positions andcharacteristics of theimages formed by aconcave lens.
Define magnification asm = v/u.
Relate focal length (f) tothe object distance (u)and image distance (v),i.e 1/f = 1/u + 1/v.
Describe, with the aid ofray diagrams, the use oflenses in optical devices.
Construct an opticaldevice that uses lenses.
Solve problems involvingto lenses.
Use an optical kit to observe andmeasure light rays traveling throughconvex and concave lenses to gainand idea of focal point and focallength.Determine the focal point and focal
length of convex and concave lenses.With the help of ray diagrams, discussfocal point and focal length.
Draw ray diagrams to show thepositions and characteristics of theimages formed by aa)convex lensb)concave lens
Carry out activities to gain an idea of
magnification.With the help of ray diagrams, discussmagnification.Carry out an activity to find therelationship between u, v and f.
