where c = is the speed of light, or 3.0 × 108m/s; λ (the Greek letter lambda) is the wavelength, often given in hundreds of nanometers in the visible light spectrum; and ν (the Greek letter nu) is the frequency, also written f and given in wave cycles per second, or s-1. ...
How many irrational numbers are there between 1 and 6? What is the conversion factor for converting meters to centimeters? How many hands is a Clydesdale? How tall is Denali? What is wavelength? If one kilometer is equal to 0.6 miles, how many kilometers would you have traveled if you ha...
matching up the peaks and troughs, the two waves are said to be “in-phase,” which, when summed, results in an even larger wave (louder sound). But what happens if you delay one of the waves by exactly one-half wavelength, matching up the troughs with the peaks of the other like...
The nature of sound is captured through its fundamentalcharacteristics: wavelength (the distance between wave peaks), amplitude (the height of the wave, corresponding to loudness), frequency (the number of waves passing a point per second, related to pitch), time period (the time it takes for ...

Night Vision Equipment and Applications Infrared Light Infrared light is a small part of the light spectrum. In order to understand night vision, it is important to understand something about light. The amount of energy in a light wave is related to its wavelength: Shorter wavelengths have hi...
NASA researchers have translated data from the Crab Nebula into sound. Panning across the image, each wavelength of light has been assigned to a different family of instruments. Light from the top of the image plays at a higher pitch, and brighter light sounds louder. ...
Since you are ideally looking to pick a supplier for the long term, you want to do business with someone who is polite, understanding, and on the same wavelength as you. Believe it or not, these little things matter a lot when it comes to doing business. ...
How to choice a lens 如何选择镜头 Choosing a Lens At first glance this seems a simple task, but you will be faced with lots of options and questions. Choose a good supplier. You will be better off talking to suppliers that design their own lenses, even if you only need an off the ...
