If an objective magnifies 40× and each binocular lens magnifies 15×, the total magnification of the object being viewed is ________.

Verified step by step guidance

1. Step 1: Understand that total magnification in a compound microscope is the product of the magnification of the objective lens and the magnification of the eyepiece (binocular lens).
2. Step 2: Identify the magnification of the objective lens, which is given as 40×.
3. Step 3: Identify the magnification of the binocular lens, which is given as 15×.
4. Step 4: Multiply the magnification of the objective lens (40×) by the magnification of the binocular lens (15×) to find the total magnification.
5. Step 5: The formula for total magnification is: Total Magnification = Objective Magnification × Eyepiece Magnification.

Key Concepts

Total Magnification

Total magnification in microscopy is calculated by multiplying the magnification power of the objective lens by the magnification power of the eyepiece (binocular lens). This combined magnification allows for a clearer and more detailed view of the specimen being observed, which is crucial for accurate analysis in microbiology.

Objective Lens

The objective lens is the primary lens in a microscope that gathers light from the specimen and focuses it to create a magnified image. Different objective lenses have varying magnification powers, and in this case, a 40× objective lens provides significant detail, making it essential for observing small microorganisms.

Binocular Lens

The binocular lens, or eyepiece, is the lens through which the viewer looks to see the magnified image produced by the objective lens. In this scenario, a 15× magnification from the binocular lens enhances the overall viewing experience, allowing for depth perception and a more immersive observation of the specimen.
