WebDec 19, 2024 · For the last question the condition for a thin prism satisfies when $\alpha$ is too small. For example about 0.8 degree for flint glass (n=1.6). For this small angle applying snell's law states that both … In a prism, the angle of deviation (δ) decreases with increase in the angle of incidence (i) up to a particular angle. This angle of incidence where the angle of deviation in a prism is minimum is called the minimum deviation position of the prism and that very deviation angle is known as the minimum angle of deviation … See more In minimum deviation, the refracted ray in the prism is parallel to its base. In other words, the light ray is symmetrical about the axis of symmetry of the prism. Also, the angles of refractions are equal i.e. r1 = r2. And, See more One of the factors that causes a rainbow is the bunching of light rays at the minimum deviation angle that is close to the rainbow angle (42°). It is also responsible for phenomena like halos and sundogs, produced by the deviation of … See more • Minimum Deviation Part 1 and Part 2 at Khan Academy • Refraction through a Prism in NCERT Tectbook • Minimum Deviation by Prism by Mark A Peterson, Mount Holyoke College See more Minimum deviation can be found manually or with spectrometer. Either the prism is kept fixed and the incidence angle is adjusted or the prism is rotated keeping the light source fixed.
