Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

We explore double and single slit example problems involving light and sound waves. In this Closer Look segment on Diffraction and Interference, we explore double and single slit example problems ...

Classical Physics (Physics established mostly by Newton), has one property that we may think that is universal, which is, certainty. For example, by using the mathematics of Newton, we can precisely ...

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...

A He-Ne laser shines on an adjustable single slit to make a diffraction pattern. The slit can be adjusted in two dimensions. Mount the laser and slit on opposite ends of the rail, making sure the ...
