The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane. For any two given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. The second law is called Snell's law after the..

Summary - Science is the way by which a person gets at the truth or at least as close to truth as possible. The basis of science is its orderly stepwise procedure - the scientific method. Scientific method employs various procedures such as, accurate observation, asking question..
Mendelian Genetics
The biggest name in the entire history of genetics beyond any doubt is that of Gregor Johann Mendel (1822-1884). It was Mendel, more than any other scientist, who synthesized the basic principles of heredity into a body of knowledge that has formed the very core of modern genetics. It mus..
Uses of Cathode Ray Tubes
They are widely used in science research laboratories by scientists for converting electrical signals into visual signals and television tubes. Doctors use them for converting electrical impulses corresponding to heart beats into visual signa..

Scientific Methodology
Science is basically a collection of knowledge and information that is obtained by observation and testing of natural world, in a logical and orderly manner, and its interpretation. Hence, the basis of science is its orderly, step-wise procedure called scientific method. I..
What is Physics?
The word 'Physics' comes from the Greek word 'phusis' meaning 'nature', introduced by the ancient scientist 'Aristotle'. Man has always been fascinated by nature. So, he questioned and sought answers for every phenomena nature could offer. The branch of science which is de..
Introduction
You have learnt in the earlier chapters that flow of electrons constitutes an electric current and current can be generated from a battery or a generator. Scientists later discovered that there are many other ways of producing the stream of electrons. This knowledge has led to further dev..

This sessions with Tutor Vista were great and the tutors really explained each problem and how we got there to solve each problem.They also let me know that they can slow down if I couldn't keep up and it made it so much easier to follow them - Hill
All the solutions that these tutors give are correct I got a 83% on my last quiz, Thank you so much - Giara
Very good tutor, I remember I have written so many times one of the best in tutor vista. Thank you so much Tutor Vista.
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
