IITJEE Advancec eligibility criteria relaxed

In a major decision, the IIT Council chaired by Union Human Resource Development minister Smriti Irani has agreed to change the IIT-JEE Advanced eligibility criteria- from the existing top 20 percentile to top 20 percentile or 75 per cent marks in the Class XII board exam, whichever is lower.

Recommended by the IIT Joint Admission Board (JAB) earlier this month, the changed JEE eligibility criteria will be a major relaxation for IIT aspirants from the CBSE board system and state boards which are seen as more generous with their marking system.

When did Bohr hydrogen atom approaches classical condition

Here our problem is to prove that the Bohr hydrogen atom approaches classical conditions when n becomes very large and small quantum jumps are involved.

To prove this let us compute the frequency of a photon that is emitted in the transition between the adjacent state

Nuclear Fission Basics

Nuclear fission is said to have occurred when nucleus of an atom splits into several small fragments. In nuclear physics nuclear fission either occurs as a nuclear reaction or as a radioactive decay process in which nucleus of an atom splits into smaller and lighter nuclei. The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a very large amount of energy even by the energetic standards of radioactive decay.

Maxwell’s Equations – Differential form of Faraday’s law (Part 6)

From the left side of the equation is nothing but the curl of the electric field and it tells about the tendency of field lines to circulate around a point . Curl of a vector means how much the vector curls around the point in question. The right side represents the rate of change of magnetic field with time. So from this it could be stated that

What does work means in physics

Work has different meaning in physics then it has in our everyday life and usage. This article is all about work and what we mean , when use term ‘work’ while studying physics. When we talk about our day to day life a person working on desktop typing is doing very less work in comparison to a person lifting and carrying heavy goods.
