Researchers at the University of Southampton have created a type of memory glass of computer that could reduce costs of medical imaging.

The team, led by Professor Peter Kazansky in the Centre for research in Photonics of the University, used nano-structures to develop millimeter devices that change the way light moves through glass.

Known as polarization glass converters space varying monolithic, these devices redirect light in 'eddies' which can then be read in a manner similar to data in optical fibers.

The information can then be written ....etc

physics practical viva questions for bsc

Q.1: Define surface tension?
Ans. The tangential cohesive force acting along the unit length of the surface of a liquid
T = F / L
Where F = total force along a line
L = length of the line
In this experiment:
F = m g = weight of the pan + weight in the pan.
L = 2 (length of the slide) + 2 (breadth of the slide).
Sometime we neglect the breadth since it is very small.

Q.2: What are units of surface tension in C.G.S. and S.I. (M.K.S.) system?
Ans. Dynes / cm (C.G.S.)
Newton / meter (M.K.S.)

Q.3: What ....etc

REDUCED EMISSIONS OF OXIDES OF NITROGEN IN SHIP ENGINES




INTRODUCTION

Oxides of nitrogen emission from ship engines are significant on a global level. These emissions participate in the formation of photochemical smog and acid rain. Here we look at to some ways by which these emissions can be reduced

Mechanism of NOx Formation in Diesel Engines

At the temperature of the Burning of fuel spray (about 2000 K to 2500 K).
Nitrogen + Oxygen Oxides of Nitrogen

Examiner (E): What was the experiment allotted to you?

Students(S): Sir, I was assigned the experiment to determine the internal resistance of a primary cell using potentiometer.
E: OK, Tell me the principle of a potentiometer

S: Sir. The principle of a potentiometer is that the potential drop across any length of a wire of uniform cross section and composition and carrying a constant current is directly proportional to the length.
E: Good. What is internal resistance?

S: The resistance offered by the electrodes and electrolyte of a ....etc
