Laser grating7/25/2023 What is the required condition for diffraction?ĭiffraction takes place if the size of the obstacle is comparable to the wave length of incident Even though source and object are at finite distance it cannot beįresnel diffraction since laser light can be focused to infinite distance. What kind of diffraction occurs in this experiment? Why?įraunhoffer diffraction. In Fresnel diffraction source and screen are at finite distance from the source whereĪs in Fraunhoffer diffraction source and screen are at infinite distance from the source.
