Question

Quizplus · Accepted Answer

Oil immersion microscopy improves both resolution and the amount of light that enters the objective lens. The oil has a refractive index similar to glass, which reduces the amount of light lost due to refraction and reflection at the glass-air interface. This creates a clear image with increased contrast and higher resolution.
