Should your hands be in front of the golf ball at address? At address, your hands should be slightly in front of the ball – exactly where you want them to return when you make contact. If it is cupped at address, you’ll be more likely to flip your wrists in the downswing and scoop […]

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? […]

What happens if you breathe in fiberglass insulation? Fiberglass Exposure Airborne fiberglass particles may become lodged in the eyeball, under the eyelid, or in the corners of the eye, causing painful irritation. When inhaled, these particles can cause irritation of the throat, nasal passages, and mouth, as well as coughing, nosebleeds, and other respiratory problems. […]

As a result, the density of rods is much greater than cones […]

What is the main point of the de Broglie equation? λ = h/mv, where λ is wavelength, h is Planck’s constant, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves. What is the de Broglie wavelength of a heavier particle? The heavier […]

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? 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 […]
