1. Radiance

   In radiometry, radiance is the radiant flux emitted, reflected, transmitted or received by a given surface, per unit solid angle per unit projected area. Radiance is used to characterize diffuse emission and reflection of electromagnetic radiation, and to quantify emission of neutrinos and other particles. The SI unit of radiance is the watt per steradian per square metre (W·sr−1·m−2). It is a directional quantity: the radiance of a surface depends on the direction from which it is being observed. The related quantity spectral radiance is the radiance of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. Historically, radiance was called "intensity" and spectral radiance was called "specific intensity". Many fields still use this nomenclature. It is especially dominant in heat transfer, astrophysics and astronomy. "Intensity" has many other meanings in physics, with the most common being power per unit area.

1. radiance

   Radiance is a measure of the intensity or brightness of light traveling from or hitting a particular surface or object in a specific direction. It measures the amount of light in watts that falls on an area in square meters from a particular direction in space, per unit of solid angle in steradians. Radiance helps to determine and quantify how much of the observer's field of view is produced by the source light.

1. Radiance

   Radiance and spectral radiance are measures of the quantity of radiation that passes through or is emitted from a surface and falls within a given solid angle in a specified direction. They are used in radiometry to characterize diffuse emission and reflection of electromagnetic radiation. In astrophysics, radiance is also used to quantify emission of neutrinos and other particles. The SI unit of radiance is watts per steradian per square metre, while that of spectral radiance is W·sr−1·m−2·Hz−1 or W·sr−1·m−3 depending on if the spectrum is a function of frequency or of wavelength.

Examples of radiance in a Sentence

1. William Wordsworth:

   What though the radiance which was once so bright Be not forever taken from my sight, Though nothing can bring back the hour Of splendour in the grass, of glory in the flower;Grief not, rather find, Strength in what remains behind, In the primal sympathy Which having been must ever be, In the soothing thoughts that spring Out of Human suffering, In the faith that looks through death In years that bring philophic mind.

2. Vincent McNabb:

   Beauty is the radiance of truth, and the frangrance of goodness.

3. Morgan Freeman:

   Learning how to be still, to really be still and let life happen - that stillness becomes a radiance. ...

4. Alfred North Whitehead:

   Nature gets credit which should in truth be reserved for ourselves: the rose for its scent, the nightingale for its song; and the sun for its radiance. The poets are entirely mistaken. They should address their lyrics to themselves and should turn them into odes of self congratulation on the excellence of the human mind.

5. Christen Kuikoua:

   Life shines its brightest when we choose to live sunny side up, letting the radiance of positivity illuminate every step. Just as the lens captures my essence in this moment, may we all capture the joy that life offers, frame by frame.
