Answer 1

Ответ:

Близорукость

-1 м

Объяснение:

Линза рассеивающая D= -1 дптр

F=1/D=1/(-1)= -1 м

Answer 2

Vision Defect and Focal Length of Prescribed Glasses

The doctor recommended that Sergey wear glasses with an optical power of -1 diopter. This indicates that Sergey has a myopic (nearsighted) vision defect. Myopia is a condition in which close objects can be seen clearly, but distant objects appear blurred.

The focal length of the prescribed lenses in Sergey's glasses can be calculated using the formula:

\[ \text{Focal length} = \frac{1}{\text{Optical power}} \]

Substituting the given optical power (-1 diopter) into the formula:

\[ \text{Focal length} = \frac{1}{-1} = -1 \, \text{meter} \]

Therefore, the focal length of the prescribed lenses in Sergey's glasses is 1 meter.
