Most sources of visible light contain energy over a band of wavelengths. Hue is thewavelengthwithin the visible-light spectrum at which the energy output from a source is greatest. This is shown as the peak of the curves of intensity in Figure 2. In this example, all three colors have the...
What two factors affect the speed of sound in the ocean? What are metastable intermediates? What kind of tumor spreads? What is the driving force of the water cycle? What is meant by signal amplification? Explain. What is stellar parallax?
Key factors of reading surf forecasts are: Swell size The size of the wave, or swell height, is a measure in feet or meters. If the surf forecast says 1-3m (3-9ft), then it's usually a good time to go surfing. 3m waves are not appropriate for beginners, but experienced surfers ...
Three types of modulation. Modulation also differs based on schemes -- the methods used to translate bits into signals. Modulation schemes can be either analog or digital. Analog scheme.Has an input wave that continuously varies, like a sine wave. ...
What three factors affect how fast a river flows? Why are sediments found in rivers? How does limestone affect geomorphology? How does sediment loss affect land and soil quality? What causes an upwelling? How do dammed rivers increase groundwater recharge and sediment transport? Why are loess se...
3) Astigmatism - for a really good lens this should be less than 1/10 wave (0.1), ideally less than 1/20 wave 4) Coma - same as astigmatism 5) Strehl ratio - ideally above 0.98. Anything lower begins to affect image quality. 0.90 is unacceptable. ...
For example, an air-dielectric device will exhibit changes in capacitance at a given setting with changes in barometric pressure, temperature, and humidity because all of these factors affect the diel
Three types of chordae tendineae can be distinguished: the primary or marginal, attached to the free leaflet margin; the secondary or intermediary, attached to the body of leaflets; and the tertiary or basal. Some chordae tendineae arise directly from the myocardial wall. The tricuspid annulus ...
Where the flags of three nations has successively waved. Wave To be moved to and fro as a signal. Wave To fluctuate; to waver; to be in an unsettled state; to vacillate. He waved indifferently 'twixt doing them neither good nor harm. Wave To move one way and the other; to brandish...
Factors such as the tension of vibrating objects and the medium through which sound travels can influence pitch. 6 How is volume measured? Volume is measured in decibels (dB), a logarithmic scale of sound intensity. 6 Can changes in medium affect pitch and volume? Yes, changes in the medium...
