Transcript of Concave Lens Magnification
Summary for the different position of object of the concave lens
Characteristics of the image formed:•Virtual•Diminished•Upright •In front of the lens
MagnificationM = D/dM= v/u
Where D = size of imaged =size of object
v=distance imageu= distance object
Relationship• Size of the image formed by the lens varied
with the object distance, u. • As the u increases, the size of the image
decreased.• The magnification value decreases if the
object moves further and further away.• The object diminished as the object distance
increases.
Application in lens in optical devices
•Microscope• Telescope• Spectacle• Binocular
