The Physics Department imparts Physics for all students of S1S2 BTech(regular). The Department of Physics was started along with the main stream in the year 1958. The department has laboratory facility for the regular B Tech students.

There are two permanent faculty members and two guest lecturers in the department. Prof Shaila K A present HoD of the department is doing research in Acoustics. Dr Shemim S S faculty of the department has done PhD in Solid State Physics with a few published works.

Dr. B. Premlet(Former HOD) has authored the following books: Advanced Engineering Physics (KU,CU,MGU & CUSAT) ,Physics for Engineers(CUSAT & MGU) , Electromagnetic Theory with Applications, Introduction to Solid State Devices, Introduction to Electrical Engineering(Co-Author).

This Department functions as a supporting department. Members of Physics department guide students in the preparation of seminars, projects and research works.

VISION

To inspire and prepare the students to meet the needs of the nation, to impart basic concepts of science to budding Engineers thus enabling them to be part of nation building.

MISSION

  • To evolve strategies in the department for providing strong foundation in physics to prepare high quality Technocrats.
  • Motivate and encourage the students to engage in lifelong learning which would help them keep abreast with contemporary developments in science to become outstanding performers in the varied careers they choose.
  • Facilitate adequate exposure to the faculty enabling them to be up-to-date with the emerging technologies.

ENGINEERING PHYSICS LABORATORY

LIST OF EQUIPMENTS

 1.Newton’s Rings apparatus

 

 

This apparatus consists of a Travelling microscope, an arrangement for the formation of Newton’s Rings (plano convex lens on plane glass plate ), and Sodium vapour  lamp. The wavelength of light from sodium vapour lamp is measured using this apparatus. This works on the principle of Thin Film Interference. We can also find the refractive index of a liquid using this arrangement. There are two units of this apparatus.The equipments  were purchased during September 2015 at a cost of Rs. 87,748.

 

  1. Air wedge Apparatus

 

The apparatus consists of two optically plane glass plates, thin wire, Sodium vapour lamp and a Travelling microscope. A thin wire whose diameter is to be determined is kept as the spacer between the two glass plates. We can find the diameter of the thin wire using air wedge arrangement.  This is an application of Thin Film Interference. Using a thin film of known thickness, we can find an unknown wavelength. There is one unit of this apparatus .The equipment was purchased during September 2015 at a cost of Rs. 50,672.

 

  1. Melde’s String

 

An Electrically maintained tuning fork in transverse mode, a stand with clamp and pulley, a light weight pan, a weight box, analytical  balance , a battery with eliminator and a long string of uniform linear density  are the elements of this experimental setup. The frequency of the tuning fork can be determined using this apparatus both in transverse mode and longitudinal mode. There are two units of this apparatus.The equipments  were purchased during September 2015 at a cost of Rs. 10,746.

 

  1. Thermocouple Apparatus

 

Experimental set up consists of a thermo couple, electric kettle, digital thermometer, digital multimeter etc. Using this set up we can study the variation of  thermo  emf with temperature. Also we calibrate it for measuring an unknown temperature. There are two units of this apparatus. The equipments  were purchased during September 2015 at a cost of Rs. 16,794.

 

5. Cathode Ray Oscilloscope( CRO  )

 

The major elements of this experimental set up are a CRO and a function Generator. A CRO consists of a Cathode Ray Tube (CRT) and associated control and input circuitry and power supplies. It is used to study the electronic waveforms visually. Waves of different shapes and sizes can be generated and their properties can be studied using CRO. There is one unit of this apparatus The equipment was purchased during September 2015 at a cost of Rs. 23,000.

 

6.Acoustic grating (Ultrasonic diffraction Apparatus).

 

The main components of this experimental  set up are Spectrometer, crystal tank(Ultrasonic transducer), oscillator etc. Using this arrangement we can determine the velocity of ultrasonic waves in a liquid. Here theory of diffraction is used. There is one unit of this apparatus. The equipment was purchased during September 2015 at a cost of Rs. 30,855.

 

7.Fraunhoffer Diffractometer

 

The experimental arrangement consists of an optical bench with fixtures and screen, Laser source, adjustable slit etc. we can find the slit width using this arrangement. This can also be used to determine an unknown wavelength if the slit width is given. Theory of diffraction is used for this experiment. There is one unit of this apparatus The equipment was purchased during September 2015 at a cost of Rs. 56,410.

 

  1. Laurent’s Half shade Polarimeter

 

Experimental setup consists of Polarimeter, Sodium vapour lamp, polarimeter tube digital balance etc. using this experimental setup we can find the concentration of an optically active solution of known specific rotatory power. This experiment is based on the theory of Polarization ( optical activity). There are two units of this apparatus. The equipments  were purchased during September 2015 at a cost of Rs. 24,899.
