Title:- Perform Science Simulations from Phet Interactive
Simulation website.
Software:-Any Web
Browser like Internet Explorer, Google Chrome, Mozilla Firefox
Aim :- To perform interactive science simulation in https://phet.colorado.edu .
Procedure :
1) Launch Internet Explorer or any other
browser.
2) Enter the URL https://phet.colorado.edu in the
address bar and press the Enter key.
3) Under how to run Simulations on Phet
Interactive Simulations Home page
Click on On Line.
4) Under Simulation Click on the Subject
you want to Explore.
5) Click on the topic name .
6) On the next page, You will see the
Simulation. You may see one or more Controls to interactively change some
parameters. You may also interactively move the objects in the simulation with
the mouse.
Geometric Optics :
1) The Geometric Optics simulations refraction through a convex lens, as
shown in the figure .
2) The simulation shows an object, its
real image and two marginal Rays. The three sliders allows to change the radius
of the curvature, refractive index and Diameter of the lens.
3) Change the radius of curvature and/
or the refractive index and see how each one affects the focal length of the
lens and hence the image distance. Click
and drag the object and /or the lens to change the object distance and note
them down.
4) Display the ruler and keep the
refractive Index Constant measure the focal length, object distance and image
distance and note them down.
5) Tabulate all the measurements.
