When light passes from a material of one refractive index to material of another, as from glass to air or from air to glass, it bends. Light of different wavelengths bends at different angles, so that as objects are magnified the images become less and less distinct.
Oil immersion is essential for viewing individual bacteria or details of the striations of skeletal muscle.

Immersion Oil contributes to two characteristics of the image viewed through the microscope: finer resolution and brightness

You're providing an air-tight seal between the slide and cover slide that reduces diffraction through several layers (air, liquid, sample surface, slide backing). It also reduces thermal perturbations from heating the sample via indirect lighting of the sample.

To straighten the light waves so that you can see at higher magnification. With that lens you can see upto 1000 times magnification. Yo can use other things instead of oil e.g. Xylene which I use quite often

it directs the light from the microscope directly to the slide and stop the light from refracting around the slide
