Convex lens-7.05-IGCSE physics
This lesson discusses all what you need to know about the convex/diverging lens within the IGCSE, 0625 syllabus
Time stamps/contents:
0:00 Introduction
0:22 (1) Nature and shape of a convex lens (converging lens)
1:39 Terms/properties of a convex lens (converging lens)
4:50 (2) Standard rays of a convex lens (what are they and how to draw)
6:26 (3) Lens image (How a lens forms an image)
8:21 Real and virtual image (difference and features)
10:54 (4) lens Image cases & applications (by changing object position)
11:25 case 1 (A real, flipped and diminished image / for camera or eye
12:53 case 2 (A real, flipped and same size image / no application)
13:26 case 3 (A real, flipped and enlarged image / for projector )
14:16 case 4 ( No image case/ no application)
15:27 case 5 (A virtual, upright and enlarged image / for magnifying glass / microscope)
16:41 Summary of cases
17:41 All cases shown
18:14 The End
The lesson includes:
convex lens / diverging lens
shape and composition of a convex lens / triangular prisms and slabs
light converge / convergence point
center point / central line / principal axis
focal point / principal focus / focal length / focal distance /f
focal length factors / lens thickness / lens material / optical density
the three standard rays of a convex lens
screen
real and / vs virtual image
light diverge
image formed vs object distance from the central line
case 1 / object far from the lens / after 2f or 2 focal lengths / camera/ eye
case 2 / object at 2f of the lens / no use
case 3 / object between 2f and f/ projector
case 4 / object at f / no image and no use / parallel light rays
case 5 / object between f and central line / magnifying glass
