## Fresnel biprism experiment - Physics - eSaral

Hey, do you want to learn about the fresnel biprism experiment? If yes. Then keep reading. Fresnel's Biprism Experiment It is an optical device to obtain two coherent sources by the refraction of lights. The angle of biprism is $179^{\circ}$ refracting angle is $\alpha=1 / 2^{\circ}$. Distance between source screen D = a + b. Distance between two coherent sources $=\mathrm{d}=2 \mathrm{a}(\mu-1) \alpha$ Where a = distance between source Biprism b = distance between screen Biprism $\mu$ = refract...
