WebJan 15, 2024 · 1D = 1 m. Thus, a value of − .5 on the ophthalmologist’s prescription can be interpreted to mean that what is being prescribed is a lens having a power of − 0.5 diopters. The minus sign means that the lens is a concave (diverging) lens. Taking the reciprocal yields: f = 1 P = 1 − 0.5D = − 21 D = − 2m. WebOptical Frequency. The optical frequency (for example of a quasi-monochromatic laser beam) is the oscillation frequency of the corresponding electromagnetic wave. For visible light, optical frequencies are roughly between 400 THz (terahertz = 10 12 Hz = 1 trillion hertz) and 700 THz, corresponding to vacuum wavelengths between 700 nm and 400 nm.
