For monochromatic light, all photons have the same energy

monochromatic rays with a frequency of 540 ´ 1012 hertz and whose energy intensity in that

In such a System blurred scatter functions are measured unless a monochromatic source of radiation is used.

a given direction, of a source that emits monochromatic radiation of frequency 5401012

The candela is the luminous intensity, in a given direction, of a source that emits monochromatic

After being pumped, the lasing medium can release that energy as monochromatic radiation.

candela: The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of

Once the laser medium is powered or pumped, it will release the energy in the form of monochromatic radiation.

The luminous efficacy Kcd of monochromatic radiation of frequency 540 × 1012 Hz is exactly 683 lumens per watt

candela: The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of

This definition implies the exact relation Kcd = 683 cd sr kg–1 m–2 s3 for monochromatic radiation of frequency = 540 x 1012 Hz.

The lumen is defined such that 683 lumens of light is provided by 1 watt of monochromatic radiation at a wavelength of 555 nm.

This definition implies the exact relation Kcd = 683 cd sr kg–1 m–2 s3 for monochromatic radiation of frequency = 540 x 1012 Hz.

A source (30) of monochromatic radiation directs a beam through a second face (11) so that it is incident on the underside of the upper surface (10) at an angle close to the angle of total internal reflection.

If monochromatic radiation irradiates the eye, as it is the case with spectral decomposition of white light, the wavelength determines which types of cones are excited.
