Amplitude

Definition

Amplitude is the height of a wave from its equilibrium point to its crest or trough. It determines the intensity or brightness of light in microscopy.

5 Must Know Facts For Your Next Test

1. Amplitude affects the intensity of light, which is crucial for visualizing microscopic specimens.
2. Increased amplitude results in brighter images when using a microscope.
3. Amplitude does not affect the wavelength or frequency of light.
4. Proper adjustment of amplitude is essential for contrast and detail in microscopy images.
5. Microscopes often have controls to adjust the amplitude to optimize sample visibility.

Wavelength: The distance between successive crests or troughs of a wave.

Frequency: The number of waves that pass a given point per second.

Intensity: The power transferred per unit area, where higher amplitude results in greater intensity.
