WebExplanation: NA = refractive index * sine (half-aperture angle). The maximum NA for a dry objective is less than 1.0 as the refractive index of air is 1. The values of NA for oil immersion lens is slightly greater than 1.0 in the range of … Webthe difference in refractive index between a living microscopic structure and its surrounding environment is so small that the structure refracts very little light. Light is, however, diffracted by the specimen. Diffracted light is, on average, slowed down by 1/4 of a wavelength relative to undiffracted light.
