Relation Between the Refractive Indices
Relation Between the Refractive Indices - According to the principle of reversibility of light, the path of a ray of light is reversible. The figure below shows how light gets refracted from medium 1 to medium ..

Electric Power - The power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flow through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electric power consumed Us..

Magnification - The ratio of the height of the image to the height of the object is called the linear magnification. It is denoted by the letter m. While deriving the mirror formula it has been proved that D ACB and D A 1 CB 1 are similar and so also D FB 1 A 1 and D FED are similar. Where h 1 is t..

Naturally occurring radioactive substances have high nucleon number. It is possible to make artificial radioactive substances by bombarding lighter nuclides with - particles, protons or neutrons. The radioactive substances produced in this manner are known as radioisotopes. A nuclide is any species..

The nucleus is made of neutrons and protons. What causes them to stick together? Why do the protons not repel each other? Surprisingly, the mass of the nucleus is less than the sum of the masses of the individual protons and neutrons which makeup the nucleus. The lost mass (mass defect) has been c..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
