What do infrared colors mean?
What do infrared colors mean? In any thermogram, the brighter colors (red, orange, and yellow) indicate warmer temperatures (more heat and infrared radiation emitted) while the purples and dark blue/black indicate cooler temperatures (less heat and infrared radiation emitted). In this image, the bright yellow area indicates the electrical fault. What color is infrared 23? […]
Why does zinc have a +2 charge?
Why does zinc have a +2 charge? Zinc has an electron configuration of [Ar] 3d10 4s2. This small amount of electrons means it is more likely to lose the 2 electrons rather than taking on any in a reaction. Losing all the electrons on the fourth shell would mean Zn lost two negative charges, making […]

What is peak wave?
What is peak wave? The peak wave period (in seconds) is defined as the wave period associated with the most energetic waves in the total wave spectrum at a specific point. Wave regimes that are dominated by wind waves tend to have smaller peak wave periods, and regimes that are dominated by swell tend to […]
How can the amount of scatter radiation reaching the IR be controlled?
How can the amount of scatter radiation reaching the IR be controlled? The radiographer must act to minimize the amount of scatter radiation reaching the IR. Beam-restricting devices and radiographic grids are tools the radiographer can use to limit the amount of scatter radiation that affects the radiographic image and exposure to the patient or […]
What will increase the effects of alcohol and drugs when boating?
What will increase the effects of alcohol and drugs when boating? Sun, wind, noise, vibration, and motion are all considered “stressors” common to the boating environment. They intensify the effects of alcohol, drugs, and some medications by causing fatigue, which greatly reduces a boat operator’s coordination, judgment, and reaction time. Do boats get you drunk […]

What will happen if two electric bulbs of 25W and 100W?
What will happen if two electric bulbs of 25W and 100W? Answer : No,25 W` bulb will fuse. From this , it is clear that voltage across the 100W bulb (=88V) is lesser than specified (220V), while across the 25Wbb̲(=352V) is greater than specified (220V), so the 25W bulb will fuse. Which bulb will glow […]
