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 higher energy. Of visible light, violet has the most energy, and red has the least. Just next to the visible...
This chart is based on the TV standard where the horizontal to vertical ratio is 4:3. Your CMOS imager may not have this ratio. Just make sure the diagonal of the imager matches the diagonal of the lens. You might be asked, “Is this a ¼ inch sensor?” This equates to a 4mm ...
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...
There is nothing like a genuine message to get you in the door.” What’s the most valuable piece of advice you could share with someone who’s looking to take their sales pitch to the next level? Don’t be scared to be yourself and think outside the box! There is nothing like a ...
The basic wave speed formula, which can be rearranged to suit your needs, is c=λν 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 ...
What is wavelength? If one kilometer is equal to 0.6 miles, how many kilometers would you have traveled if you have traveled 42 miles? How many leap years have there been? How many milliliters in a liter? How many leap years in 100 years?
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...

What treatments or methods are available to mitigate hearing loss? How does your brain generate electricity? How and why does the tidal range vary between a spring tide and a neap tide? Why do we say that light travels in wavelengths? What is a wavelength of light?
