Explain why an oil immersion lens works better with oil than with air between the specimen and the lens.

Question

Accepted Answer

∻Answer∻ ⚹ An oil immersion lens works better with oil than with air between the specimen and the lens because oil has a higher refractive index than air, which reduces light refraction and increases resolution. ⚹ ∻Solution∻ ‖ a ⋮ Refractive Index: Oil has a higher refractive index (approximately 1.5) compared to air (approximately 1.0). This minimizes the bending of light rays as they pass from the specimen to the lens, allowing more light to enter the lens. ‖ ‖ b ⋮ Resolution: The use of oil reduces the loss of light due to refraction, which enhances the numerical aperture of the lens. This results in better resolution and clearer images of the specimen. ‖ ∻Key Concept∻ ⚹ Refractive Index ⚹ ∻Explanation∻ ⚹ Oil has a higher refractive index than air, which reduces light refraction and increases the amount of light entering the lens, thereby improving resolution. ⚹◊How does the refractive index of oil compared to air affect the resolution of the oil immersion lens?⍭ Generate me a similar question◊
