How do you prevent chromatic aberration in glasses?

How do you prevent chromatic aberration in glasses? Try a smaller frame with smaller lenses. CA and distortion is most apparent when you’re not looking with your eyes pointed forward.. Also, try lenses with a higher abbe value. I already tried CR-39 lenses, which is the material with the highest abbe value, and it’s not […]

How do you find speed when given height?

How do you find speed when given height? Multiply the height by the object’s acceleration due to gravity. The acceleration due to gravity is 32.2 ft/s^2 for English units, or 9.8 m/s^2 for SI units. If you drop an object from 15 feet, for example, you would multiply 15 ft * 32.2 ft/s^2 to get […]
