Document Summary
Wavelength distance between one peak of a wave and the next peak. Frequency rate of vibration of the wave. Absorbance material captures the energy of a light wave. Interference light waves interaction with each other. Diffraction light waves interact with small objects by bending or scattering. Refraction light waves change direction as they enter new medium. Uv light: fluorescent dyes absorb uv waves and use the energy to emit photons of a differ ifferent color. Magnification ability of a lens to enlarge an image of an object when compared to the re. Resolution the ability to tell that two separate objects are separate objects. Contrast visible differences between structures in a specimen. Renders a darker image on a lighter background, producing a clear image of cells. Increases contrast, rendering a brighter image on a darker background contains a modification that only allows focused light on the specimen. Alters the wavelength of light passing through specimen.
