Scope and
Purpose of the Project
We are
developing a project for optical lenses, mirrors, prism and optical-fiber
experiments simulation. It will be like getting image and ray diagram for
object's position from lenses (biconvex, biconcave, Plano-Convex,
Convex-Concave, Meniscus, Plano-Concave), mirrors (concave, convex, plane),
prism and optical-fiber. We made that dynamic like we can drag the object
towards or backward from lenses, mirrors, prism and optical-fiber. We used
Html5, kineticjs (JavaScript library) and CSS3 to develop this. We are
contributing this project for Mozilla Science Lab.
Process
Overview Project
There will
be four categories of experiments. Lens, Mirror, Prism and Optical-fiber. In
lens experiment, there are six categories with biconvex, biconcave,
Plano-Convex, Convex-Concave, Meniscus, Plano-Concave lenses. In two lenses
experiment, there are numerous categories with the pairs like (biconvex,
biconvex), (biconcave, biconcave), (biconvex, biconcave), (biconcave, biconvex)
and etc. In mirror experiment, there are three categories with convex, concave
and plane. In prism experiments, there are two types of experiments. One is for
finding angle of deviation. And another is for finding deviation of colors.
Optcal-fiber experiment is also there. This is for finding the reflection
inside the optical-fiber. Lens and mirror are working as five different cases
such as object beyond 2F, object between F and 2F, object at 2F, object at F,
object within F.
Introduction
the Structure of Interface
This
application consist Experimental area, Lenses, Mirror, Prism and Optical-fiber
Toolbar, Objects Toolbar and Help button. We can perform simulation in this
Experimental Area. In the lenses toolbar types of lenses are shown such as
biconvex, biconcave, Plano-Convex, Convex-Concave, Meniscus, Plano-Concave. In
the mirror toolbar, types of mirror are shown such as convex, concave, plane.
In prism toolbar prism and in the mirror toolbar optical-fiber are shown. In
the object toolbar there are three objects, they are Arrow, Triangle and Polygon.
To get Help, there is an icon with question mark.
How to
insert Lens and Object to the experimental area
There is
horizontal line placed in the experimental area and that is center axis of
lens. We can drag and drop lens, mirror, prism and optical-fiber from lens,
mirror, prism and optical-fiber toolbar. We can have maximum of two lenses in
experimental area. You can add them by drag and drop wherever you want and
which order you want. You can replace these lenses by drag and drop the wanted
lens over or near to the existing lens. After you added lens the ‘F’ and ‘2F’
will be added in both side of the lens. If you add second lens, F and 2F of
each lens’s color will be different. So, you can easily identify F, 2F for
corresponding lens. In objects tool bar three objects are placed. You can
select one of these objects by clicking the corresponding icon to get the
object in experimental area. You can add only one object at a time. if you
click on the other object, the existing object will be replaced by new object.
Mirrors are also working like lenses. For prism there are one object. You can
drag and drop the prism from prism toolbar and click the oject. If you move the
object the ray diagram will be shown for prism. You can find the angle of
deviation and in spectrum you can find the deviation the color. For
optical-fiber you have to do the same and you can see the reflection inside
optical-fiber.
How to
adjust the Object
Optics will
be placed in center of the experimental area and they can drag only in horizontal
axis. You can drag the optics within the range of between object and end of the
experimental area. If there are two lenses, first lens can move between object
and second lens’s position. Second lens can move between first lens’s position
and end of the experimental area. So we can change the distance between the
lenses. Object can be move between starting of the experimental area and lens’s
position. So, we can change the distance from the lens. And you can identify
the object’s position such as beyond 2F, between 2F and F, within F by looking
at theF,2F marks. While you drag lens or object you can see the ray diagram and
the image generated by lens for corresponding object will appear dynamically.
For mirror also the same. You can see the ray diagram and the image generated
by mirrors for corresponding object will appear dynamically. For prism you can
drag the prism and click the object. The object will move in up sight and down
sight. You can see the ray diagram and colors in spectrum. For optical fiber,
object will be in same place. You have to click the object and you can see the
reflection.
How to
remove Lens, Mirror, Prism and Optical-fiber
To remove a
lens, mirror, prism and optical-fiber from the experimental area just double
click on the lens.
