Activity 6.17 ICS

Aim: To draw ray diagrams to show the image position and Simulation of images for
determine the characteristics of images formed by a concave mirror and
concave mirror and a convex mirror
convex mirror
Instructions:

1. Work in groups.
2. Visit the websites given and carry out the simulation in http://bt.sasbadi.com/p4273a
the websites.

3. Based on the simulation, complete Table 6.14 and Table Download Table 6.14 and
6.15. You can download and print the tables from the Table 6.15
websites given.

4. Draw ray diagrams to show the image position and state
the characteristics of images formed by concave mirror
and convex mirror. http://bt.sasbadi.com/p4273b
