Free Vibrations: If a given body is once set into vibrations and then let free to vibrate with its own natural frequency, the vibrations are said to be free vibrations. The natural frequency of free vibrations depends on the nature and structure of the body and in ideal situation, the amplitude, frequency and the energy Read more about Free, Forced, Damped and Resonant Vibrations[…]
Hello MyRank Viewers, here are Some Important Qualitative Analysis Tests and Results 1. CHARCOAL CAVITY TEST: Residue Metallic Bead Inference Yellow when hot, white when cold Zn2+ Brown when hot, yellow when cold Green bead, Makes the paper black Pb2+ No characteristics residue Red beads / scales Cu2+ White residue, glows on heating Ba2+/ Sr2+/ Read more about Some Important Qualitative Analysis Tests And Results………[…]
Hello MyRankers, here is the explanation of YOUNG DOUBLE SLIT EXPERIMENT 1. In Young’s double slit experiment, if monochromatic light is replaced by white light then central fringe will be white; all other fringes will be coloured. White light consists of colours between violet and red (VIBGYOR). Wavelength λ is the shortest for violet light and Read more about YOUNG DOUBLE SLIT EXPERIMENT[…]
Ever wondered why Thermo Dynamics is named so? THERMO → Heat, Dynamics → Motion or flow Basically, thermodynamics deals with all changes in energy or transfers of energy that accompany physical and chemical processes. Important terms in Thermo Dynamics: System, surrounding and Boundary: A system is defined as specific part of matter which is under experimental investigation and the Read more about Thermo dynamics[…]
Hello MyRankers, Here is the explanation of Geometric Progression…… A sequence of non-zero numbers is called a geometric progression (abbreviated as G.P.). If the ratio of a term and the term preceding to it is always a constant quantity. The constant ratio is called the common ratio of the G.P. In other words, a sequence, a₁, a₂, Read more about GEOMETRIC PROGRESSION[…]
Characteristics of EM waves: 1. Electromagnetic waves are transverse in nature. They are produced by varying electric and magnetic fields. In an electromagnetic wave, the electric and magnetic fields oscillate perpendicular to each other as well as perpendicular to the direction of propagation of the wave. Both electric and magnetic fields vary in phase with Read more about Hello MyRankers, here is the explanation of EM waves characteristics…….[…]

MUMBAI: Twelve-year-old Maryam Siddiqui is a rank holder at the exams in school. But recently, the class VI student Read more about Muslim Girl In Mumbai Wins Gita Contest…[…]
Introduction: Sequence: A sequence is a function whose domain is the set N of natural numbers. Real Sequence: A sequence whose range is a subset of R is called a real sequence. In other words, a real sequence is a function with domain N and the range a subset of the set R of real numbers. Read more about SEQUENCE AND SERIES[…]
LEARN FROM MISTAKES Thomas Edison tried two thousand different materials in search of a filament for the light bulb. When none worked satisfactorily, his assistant complained, “All our work is in vain. We have learned nothing.” Edison replied very confidently, “Oh, we have come a long way and we have learned a lot. We know Read more about “No one in the world get succeed in the first attempt. Those who learn things from their mistakes can only lead to success”. To know read this short story.[…]
