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.

Carry out activities to gain an idea onthe of lenses in optical devices.

With the help of ray diagrams discussthe use of lenses in optical devicessuch as a telescope and a microscope.

Construct an optical device that useslenses.

Solve problems involving lenses.
