       How to draw the Ray Diagram for Reflection at a plane                   surface based on Huygens’ Principle ?                                 - Smarter Techniques   Laws of reflection :  1  Angle of incidence i = Angle of reflection r  2  Incident, Reflected ray & normal are in one plane. Huygens’ Principle: "  Every point on wave-front acts as secondary source and sends secondary waves in all directions. " Using this principle Laws of Reflection can be proved. In my blog related to   How to Draw Diagrams in Physics  by Smarter Techniques ,  I have  discussed about general guide line to draw diagrams on A4 sheet. Do you want to know " How to draw the Ray Diagram for Reflection at a plane surface based on Huygens’ Principle ? " using given guide line...

  How to draw   Diagrams for   Modes of vibrating Air column in a tube open at both ends ?  -  Smarter Techniques     Air column of length L is formed in a tube open at both ends. This air is made to vibrate by tuning fork . Then the air column will vibrates in different modes. Fundamental or 1 st       |       2 nd  Harmonic     |    3 rd Harmonic             Let   V be the velocity of sound waves in air then fundamental frequency n is given by Second harmonics frequency Then the frequencies are   1 st , 2 nd , 3 rd … Harmonics. Thus Air column in a tube open at both ends vibrates with all harmonics. In my blog related to   How to Draw Diagrams in Physics   by Smarter Techniques ,   I have   discussed about general guide line to draw ...
