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.

Radius of Curvature(m)	Refractive Index	Focal Length (cm)	Object Distance (cm)	Image Distance (cm)
0.7	1.55
0.9	1.55
0.7	1.7
0.9	1.7
