GUIDE QUESTIONS
1. How does varying locations of the light sources with respect to the photometer affect the results of the
experiment?
Changing the distances of the light sources affects the experiment by
increasing the intensity of the light going in th

GUIDE QUESTIONS
1. In the experiment, is the image formed real or virtual? Justify your answer.
Real Image is produced. In the mechanism of refraction, when light strikes the
convex lens, the path of light is refracted at a certain focus going down. It wi

Guide Questions
1.) How does slit width affects the result of the experiment?
How about slit screen separation? Are the experiment results
consistent with the theory?
In the width of the slit, as the size of the minimum and maximum
increases as the width
GUIDE QUESTIONS
1. If the transparent material has an index of refraction of 1.6, what is the angle of incidence beyond which
total internal reflection occurs?

2. Is it possible for the critical angle to exist when light goes from
ANALYSIS

No, convex mirror always form virtual images because light rays
parallel to principal axis are reflected from the mirror and they do
not meet. They appear to be coming from a poi
