light intensity and pulverizzers

optics - Light intensity through polarizers and a diffuse ...

The directly reflected light retains its polarisation so can be blocked by choosing $\theta=90^o$. The diffused light is unpolarised so half of it is lost in the second polariser. Of course, if your light source is unpolarised to begin with, you also lose half of the overall intensity in the first polariser.

Pulsar - Wikipedia

A pulsar (from pulse and -ar as in “quasar”) is a highly magnetized rotating compact star (usually neutron stars but also white dwarfs) that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing toward Earth (similar to the way a lighthouse can be seen only when the light is pointed in the direction of an ...

Noise levels of can be an influential factor in purchasing a generator set. The manufacturer records sound pressure levels at fixed distances around the generator set and averages them to calculate the levels. It is critical to calculate the logarithmic mean of the measurements, not the arithmetical mean, to avoid having the generator set appear quieter on paper than in practice.

As far as I know, brightness is defined in optics as a component of color. Therefore it depends not only on the intensity of the light, but on our perception of it. It is more closely related to luminous intensity than to radiant intensity.For a beam with a given spectrum, however, the luminous and radiant intensities will be related by fixed proportionality.
