Syllabus for IGNOU BSc Physics - Physics Laboratory-I BPHL-103

Observation and experimentation are the two characteristic features of science. Prior to Galileo, scientists based their theories on speculation and aesthetic preferences. He broke away from this tradition. Ever since, it has become a standard method of science to accept theoretical predictions only if repeated observations and precise measurements provide enough evidence. Indeed as Lord Kelvin so aptly put it. "When you can measure what you are speaking about and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind."

IGNOU BSc Physics - Physics Laboratory-I BPHL-103

As a student of science in IGNOU, and particularly physics, you must aim to be a skilled observer and experimentalist. BPHL-103 is the first laboratory  course in physics. This course should enable you to:

  1. Gain experience in the scientific method viz. taking unbiased  observation, interpreting and analyzing data and deriving conclusions
  2. Acquire basic skill in using different measuring  instruments
  3. Learn some standard techniques for the measurements of various physical quantities.

To achieve these objectives, preset and open-ended experiments have been designed for this course. These experiments pertain to oscillations, waves and mechanical and electrical properties of materials.

As you work through this course, you will realise that a lot of good physics can be learnt through simple experimental  arrangements.
