What are the magnifications of the objective lenses on the microscope used in lab?

The correct answer is based on the standard magnifications typically found on microscopes used in introductory biology labs. The most commonly utilized objective lenses include 4x, 10x, 40x, and 100x.

The 4x lens is often used for scanning larger specimens, allowing for a broad overview. The 10x lens magnifies further, making it suitable for viewing more detailed structures. The 40x lens provides even greater magnification, typically used for examining biological samples with more complexity, while the 100x lens, usually an oil immersion lens, allows for the highest resolution, important for viewing very fine details in specimens.

These standard magnifications are well-suited for educational purposes, enabling students to observe a variety of specimens across different levels of detail, which aligns with the educational goals of introductory biology courses.
