Question

RESOLUTION: This property of the compound microscope is the degree to which the detail in the specimen is retained in the magnified image. It is the ability of a microscope to distinguish two closely spaced objects as separate and distinct entities. Conventional light microscopes have a resolution of about 0.2 μm. RESOLVING POWER (d) is the closest spacing between two points at which the points can still be seen rly as separate entities. The smaller the resolving power, the smaller the object that can be seen distinctly. The resolving power of a light microscope depends on the wavelength of light (Q) and a property of the objectiv resolving power of a light microscope is: d -o.5/NA or d /2 NA. (BLM p 5) WAVELENG wavelengths in the visible spectrum. The shortest spectrum (400 nm) illuminating the power of a microscope. What is the wavelength of blue light? e lens called the numerical aperture (NA). The formula for calculating the approximate TH OF LIGHT (Q): The light source for optical microscopes consists of a band of colored visible wavelengths are in the violet-blue portion of the and the longest are in the red portion (750 nm). The shorter the wavelength of light imen and the greater the value for the numerical aperture, the better the resolving Is there a blue filter on your microscope? or decrease if a red filter was used? ould the res resolving power of the microscope increase nanometers (nm) in 1 micrometer (μm) give the wavelength of blue light in both nm and Which of these units is generally used to describe the size of bacteria? PERTURE: The numerical aperture, generally abbreviated NA, is the light-gathering
