Contact uS *These questions are expected for the exams This may or may not be asked for exams

    All the best.... from admin Santhosh

          Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements 

If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates                                                      ~$tuff$£ctor

UNIT I MECHANICS

Multi-particle dynamics: Center of mass (CM) – CM of continuous bodies – motion of the CM –

kinetic energy of the system of particles. Rotation of rigid bodies: Rotational kinematics – rotational kinetic energy and moment of inertia - theorems of M .I –moment of inertia of continuous bodies – M.I of a diatomic molecule - torque – rotational dynamics of rigid bodies – conservation of angularmomentum – rotational energy state of a rigid diatomic molecule - gyroscope - torsional pendulum

– double pendulum –Introduction to nonlinear oscillations.

UNIT II ELECTROMAGNETIC WAVES

The Maxwell’s equations - wave equation; Plane electromagnetic waves in vacuum, Conditions on

the wave field - properties of electromagnetic waves: speed, amplitude, phase, orientation and

waves in matter - polarization - Producing electromagnetic waves - Energy and momentum in EM

waves: Intensity, waves from localized sources, momentum and radiation pressure - Cell-phone

reception. Reflection and transmission of electromagnetic waves from a non-conducting medium-

vacuum interface for normal incidence.

UNIT III OSCILLATIONS, OPTICS AND LASERS

Simple harmonic motion - resonance –analogy between electrical and mechanical oscillating

systems - waves on a string - standing waves - traveling waves - Energy transfer of a wave - sound

waves - Doppler effect. Reflection and refraction of light waves - total internal reflection -

interference –Michelson interferometer –Theory of air wedge and experiment. Theory of laser -

characteristics - Spontaneous and stimulated emission - Einstein’s coefficients - population

inversion - Nd-YAG laser, CO2 laser, semiconductor laser –Basic applications of lasers in industry.

UNIT IV BASIC QUANTUM MECHANICS

Photons and light waves - Electrons and matter waves –Compton effect - The Schrodinger

equation (Time dependent and time independent forms) - meaning of wave function -

Normalization –Free particle - particle in a infinite potential well: 1D,2D and 3D Boxes-

Normalization, probabilities and the correspondence principle.

UNIT V APPLIED QUANTUM MECHANICS
