A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion
of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form
of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky
directly opposite the sun.
Objective: This research reveals the physics behind the creation of rainbows and to find out "Is the artificial
creation of rainbows help full in any way when it comes to our understanding of ways in which light works.
A project to:
Determine the dependence of the sample stream on the voltage at zero magnetic induction.
Find the dependence of the Hall voltage on the magnetic induction at two values of constant current sample.
Process the measurement results graphically and evaluate conductivity and Hall effect sample.
Calculate the mobility and concentration of charge carriers.
Solving the physics problems you are presented with in an introductory course
become easier if each time you sit down to solve a problem, you follow a
generalized problem-solving strategy that includes sketching pictures.
Web security issues remain a major challenge with numerous security concerns, Distributed Denial of Service Attack (DDos) leads among these. It was evolved from DOS and its main purpose is to consume large amount of server resources so that the server cannot provide service to normal users. Attackers usually gain access to large number of computers by exploiting the vulnerabilities to set up attack armies (i.e., Botnets). This paper will review and analyse different existing DDoS detecting techniques against different parameters, and propose a new hybrid architecture for the defence mechanism of DDoS attack.
Here we discuss the path integral formalism for quantization of fields. The basic idea is reviewed and explained. This is completely based on the book ``Quantum Field Theory A Modern Introduction" by Michio Kaku. For calculation natural system of units is taken.
