I want solutions for the attach problem. It’s urgent. Please try to submit within time frame.
1. Parallel light rays are falling on the plane surface of a semi-cylinder made of glass, at
an angle of 45, in such a plane which is perpendicular to the axis of the semi-cylinder
(Fig. 4). (Index of refraction is
.) Where are the rays emerging out of the
cylindrical surface? 2. Three closed boxes (black boxes) with two plug sockets on each are present for
investigation. The participants have to find out, without opening the boxes, what kind
of elements are in them and measure their characteristic properties. AC and DC
meters (their internal resistance and accuracy are given) and AC (5O Hz) and DC
sources are put at the participants? disposal.
