Physics Lab

The Physics lab consists of animations that we use everyday in real life - some of which we take for granted, without thinking much about it. The animation on the humble electric bell is a case in point.

There are animations to demonstrate loudspeaker, electromagnetic relay, electromagnetic induction, and X-ray production.

Moreover, there are two programmes: one for the calculation of the temperature of a distant star; the other for making colours from primary colours .

The Casual Astronomer



Calculate the temperature of a distant star - yes, it is feasible; no gimmick.

Look at your favourite star for a few seconds and then get an idea about its colour. Afterwards, look at the following table and find the nearest wavelength that corresponds with the colour.


  1. Put the wavelength in the textbox
  2. The temperature will be calculated automatically in the other textbox
  3. No sophisticated equipment; no complex calculations

The Colour Maker



Do you know that, each colour you see around you are a combination of just three colours? These three 'major players' are called Primary Colours.
The three primary colours are Red, Green and Blue.
This programme lets you mix them as you wish and produce the colour accordingly.
You will not believe your eyes! you can produce millions of colours, using this tiny programme.
Enter a number less than 256 into each text box and mix; you tap on, one of the millions!

Boyle's Law

The volume of a fixed mass of gas is inversely proportional to its pressure at constant temperature.

 

p ∝ 1 / v
p = k 1 /v
pv = k

Please move the slider and experiment with it.

P ∝ 1 / V




 

 

 

 

Resources at Fingertips

This is a vast collection of tutorials, covering the syllabuses of GCSE, iGCSE, A-level and even at undergraduate level. They are organized according to these specific levels.
The most popular tutorial is the Book of Electricity, which comes at the top of Google search for electricity tutorials for GCSE / AS/ A-Level at present.
In addition, there are a few more which come at the top of Google search.They are all supported by an extensive collection of animations and interactive labs.

Recommended Reading

 

The best book for both teachers and students to learn physics - exactly like in good old days:concepts are clearly explained in detail;no meaningless cartoons to devour space;the author rendered a great service in his unique approach for generations of students, with this being the fourth edition.
