Wave Optics From RGPV Engineering Physics Notes

1    UNIT – 2    WAVE OPTICS   Unit-02/Lecture-01    FRESNEL BIPRISM:-  Fresnel’s biprism is made by joining two thin prisms at their base to create a single  triangular shape. Light from single slit S forms spherical waves incident on the biprism.  Light passing through the lower section is refracted up, while light going into the top  section is refracted down, forming a region where the beams interfere. This creates two  virtual sources  S 1   and S 2 , with an apparent separation a. A biprism is essentially two  prisms, each of very small refractive angle α placed base to base. In reality the biprism is  constructed from a single plate of glass by suitable grinding and polishing it; the obtuse  angle of the prism is only slightly less than 180° and the other angles is of the order of 30’  are equal.                  … Read more

Quantum Physics – RGPV Engineering Physics Notes

1    UNIT – 1     QUANTUM PHYSICS  Unit-01/Lecture-01    Concept of matter waves  Louis de Broglie made the suggestion that particles of matter, like electrons, might possess wave properties and hence exhibit dual nature. His hypothesis was based on the following arguments:    The Planck’s  theory  of  radiation  suggests  that  energy    is quantized and is given by    E = h ν  (1)     where ν is the frequency associated with the radiation.  Einstein’s mass-energy relation states that                        E = mc 2    … Read more
