In Viewing a Microscopic Specimen, Oil is Used To

Question

In viewing a microscopic specimen, oil is used to
A) increase the refraction AND increase the reflection.
B) decrease the refraction AND increase the reflection.
C) decrease the refraction AND increase the resolution.
D) increase the reflection AND increase the resolution.
E) increase the resolution AND increase the refraction.

Accepted Answer

Oil is used to decrease the refraction between the specimen and the objective lens, which increases the resolution of the image. By reducing the refraction, more light is able to pass through the specimen and enter the lens, resulting in a clearer image.
