NCERT Class 11 Physics Lab Manual: Physics deals with the study of matter and energy. The aim of performing practical work in physics is to verify concepts and principles. Understanding the importance of lab work, the Central Board of Secondary Education (CBSE) has given a comprehensive list of exercises. To help the students, here we have provided the exercise files in both English and Hindi in PDF format.
NCERT has explained, ‘’The history of science reveals that many significant discoveries have been made while carrying out experiments. In the growth of physics, experimental work is as important as the theoretical understanding of a phenomenon. Performing experiments by one’s own hands in a laboratory is important as it generates a feeling of direct involvement in the process of generating knowledge. Carrying out experiments in a laboratory personally and analysis of the data obtained also help in inculcating scientific temper, logical thinking, rational outlook, sense of self-confidence, ability to take initiative, objectivity, cooperative attitude, patience, self reliance, perseverance, etc. Carrying out experiments also develops manipulative, observational and reporting skills. The basic purpose of a laboratory manual in physics is to motivate the students towards practical work by involving them in “process-oriented performance” learning (as opposed to ‘product-or result-oriented performance’) and to infuse life into the sagging practical work in schools.’’

Objectives of Practical Work
| The learner develops manipulative skills in practical work if she/he is able to- comprehend the theory and objectives of the experiment; conceive the procedure to perform the experiment; set-up the apparatus in proper order; check the suitability of the equipment, apparatus, tool regarding their working and functioning; know the limitations of measuring device and find its least count, error etc.; handle the apparatus carefully and cautiously to avoid any damage to the instrument as well as any personal harm, perform the experiment systematically; make precise observations; make proper substitution of data in formula, keeping proper units (SI) in mind; calculate the result accurately and express the same with appropriate significant figures, justified by the degree of accuracy of the instrument; interpret the results, verify principles and draw conclusions; improvise simple apparatus for further investigations by selecting appropriate equipment, apparatus, tools, materials. |
| The learner develops observational skills in practical work if she/he is able to- read about instruments and measure physical quantities, keeping least count in mind; follow the correct sequence while making observations; take observations carefully in a systematic manner; minimize some errors in measurement by repeating every observation independently a number of times. |
| The learner develops drawing skills for recording observed data if she/he is able to-make schematic diagram of the apparatus; draw ray diagrams, circuit diagrams correctly and label them; depict the direction of force, tension, current, ray of light etc, by suitable lines and arrows; plot the graphs correctly and neatly by choosing appropriate scale and using appropriate scale. |
| The learner develops reporting skills for presentation of observation data in practical work if she/he is able to- make a proper presentation of aim, apparatus, formula used, principle, observation table, calculations and result for the experiment; support the presentation with labelled diagram using appropriate symbols for components; record observations systematically and with appropriate units in a tabular form wherever desirable; follow sign conventions while recording measurements in experiments on ray optics; present the calculations/results for a given experiment along with proper significant figures, using appropriate symbols, units, degree of accuracy; calculate error in the result; state limitations of the apparatus/devices; summarize the findings to reject or accept a hypothesis; interpret recorded data, observations or graphs to draw conclusion; explore the scope of further investigation in the work performed. |
Specific Objectives of Laboratory Work
| The learner develops process-oriented performance skills in practical work if she/he is able to- select appropriate tools, instruments, materials, apparatus and chemicals and handle them appropriately; check for the working of apparatus beforehand; detect and rectify instrumental errors and their limitations; state the principle/formula used in the experiment; prepare a systematic plan for taking observations; draw neat and labelled diagram of given apparatus/ray diagram/circuit diagram wherever needed; set up apparatus for performing the experiment; handle the instruments, chemicals and materials carefully; identify the factors that will influence the observations and take appropriate measures to minimize their effects; perform experiment within stipulated time with reasonable speed, accuracy and precision; represent the collected data graphically and neatly by choosing appropriate scale and neatly, using proper scale; interpret recorded data, observations, calculation or graphs to draw conclusion; report the principle involved, procedure and precautions followed in performing the experiment; dismantle and reassemble the apparatus; follow the standard guidelines of working in a laboratory. |
| The learner develops product-oriented performance skills in practical work if she/he is able to- identify various parts of the apparatus and materials used in the experiment; set-up the apparatus according to the plan of the experiment; take observations and record data systematically so as to facilitate graphical or numerical analysis; present the observations systematically using graphs, calculations etc. and draw inferences from recorded observations; analyze and interpret the recorded observations to finalize the results; accept or reject a hypothesis based on the experimental findings. |
