6 Questions
Why is oil used on the slide when examining with the oil-immersion objective?
To reduce light refraction between air and glass
What is the purpose of using an oil-immersion objective when studying microbes?
To clearly observe fine details of microbial morphology
Why should the body tube of the microscope not be lowered while looking through the ocular lens?
To maintain a specific working distance between the lens and the slide
What does a high-power objective lens do to image quality in a microscope?
Improves image resolution by reducing light refraction
Which component of a microscope is crucial for observing fine details in biological samples at high magnification?
Oil-immersion objective
What happens to image quality if there is air between a high-power objective lens and a slide?
Image quality reduces due to excessive light bending
Learn why oil is used on the slide with the oil-immersion objective in microscopy. Understand how light refraction affects image quality and how using oil can produce sharper, higher-resolution images of tiny structures on the slide.
