UTA Microbiology Chapter 2 Exam
Questions & Solutions
Reflection - -The bouncing back of a wave when it hits a surface through
which it cannot pass.
- Transmission - -the passage of light through an object
- Interference - -the combination of two or more waves that results in a
single wave
- Diffraction - -The bending of a wave as it moves around an obstacle or
passes through a narrow opening
- Refraction - -Change direction and or speed
- refractive index - -a measure of the light-bending ability of a medium
- Refractive index equation - -300,000kps/speed kps
- convex lens - -A lens that is thicker in the middle than at the edges
Magnify
- concave lens - -A lens that is thinner in the center than at the edges
Reading glasses
- Frequency increases from - -Violet to red
- Magnification - -An increase in the apparent size of an object
- contrast - -Stark difference in coloration
- Resolution - -Ability to tell two separate points
- shorter wavelength - -Higher resolution
- longer wavelength - -lower resolution
- numerical aperture - -the ability of a lens to gather light
- First simple microscope - -Leeuwenhoek
