Question 1: Explain a major difference between diffraction and interference?Īnswer: One major difference between diffraction and interference is with regards to their occurrence. In contrast, destructive interference happens when the two superposing waves are of the opposing phase but have the same amplitude. Constructive interference happens when the two superposing waves are of the same phase and amplitude. These two categories are constructive interference and destructive interference. The classification of interference can take place into two categories. Therefore, the superposition of the waves provides the algebraic addition of the existing disturbances because of the presence of separate waves. Most noteworthy, coherent sources provide a light wave of constant phase difference and the same frequency.Īlso, two waves that are coherent in nature will always superpose each other whenever their crossing takes place. Furthermore, these light waves travel in the same medium. Interference refers to the act of superposition of multiple light waves whose emission takes place by two coherent sources. Consequently, the spreading of the wave will take place over the entire surface or material after the slit. When we take into consideration the very small dimension of the slit, the opening will tend to act as a separate source. Also, the bending is significantly noticeable in the case of opening that is smaller. This is certainly similar to the case of the large opening. Also, the wavelength should be comparable with all the slit’s dimensions.Īn important fact to understand is that light wave does not bend at the edges. The contrast between maxima and minima is certainly goodĪn important answer will be to the question- what is diffraction? Well, it is certainly the phenomenon of light wave spreading when its passing takes place through a small gap or slit. The contrast between maxima and minima is poor Same fringe intensity for all the fringes

Not same, in case of diffraction, for all fringes It occurs due to the light waves superposition that is from two sources It occurs because of the secondary wavelengths superposition Important difference between diffraction and interference Parameter Difference between Diffraction and Interference Moreover, this shape is due to the net effect of two individual waves on the medium’s particles. Furthermore, the interference causes the medium to take a particular shape. Interference refers to the phenomenon that takes place due to the meeting of the two waves takes as they travel along with the same medium. Furthermore, it takes place when the travelling wavelength’s part gets obscured. In case the size of the obstacle or aperture is of similar linear dimensions to the incident wave’s wavelength, then its occurrence would be significant. 3.2.1 FAQs about Diffraction and Interference Definition of Diffractionĭiffraction refers to the spreading out of waves when their passing takes place through an aperture.
