Concise Explanations of The Kinetic Theory of Saturation
The kinetic theory of saturation can best be explained when we consider a vapor in contact with its liquid, in an otherwise empty vessel which…

Application of Fraunhofer Lines and Kirchoff’s Laws in Spectrum Analysis
Fraunhofer Lines: In 1814 Fraunhofer noticed that the sun’s spectrum was crossed by many hundreds of dark lines. These Fraunhofer lines, as they are called,…
Room Reverberations, Acoustics and Sabine Investigations
A concert-hall, lecture-hall, or a broadcasting studio requires special design to be acoustically effective. The technical problems concerned were first investigated in 1906 by Sabine…
The Production and Uses of Ultrasonics
What are Ultrasonics? Ultrasonics are sound waves of higher frequency than 20000 Hz, which are inaudible to a human being. These are known as ultrasonics; and…
How to Measure the Velocity of Sound in Free Air Using Hebb’s Method
In 1905 Hebb carried out an accurate experiment to determine the velocity of sound in free air which used a method of interference. He carried out…
How to Measure the Velocity of Sound in a Quincke Tube
Quincke devised a simple method of measuring the velocity of sound by obtaining permanent interference between two sound waves. He used a closed tube SAEB…
Observation of Reflection and Refraction with a Thermopile
What is a thermopile? A thermopile is a set of thermocouples that has been designed and arranged to measure little quantities of radiation or radiant…
The Linde Process and its Significance in Gas Cooling
Description of the Linde Process in the Cooling of Gases The cooling of a gas in a free expansion is small but Linde in his…
How a Refrigerator Works and the Liquefaction of Gases
The science behind how a refrigerator works is a novel area of study that physicists have continued to improve upon, delivering very efficient and smart…
How to Measure the Partial Pressure of Atmospheric Water
The water vapor in the atmosphere is important because it affects our comfort. Except in cold weather, we sweat continuously: the water in the sweat…
