Intensity and luminosity
WebLuminous intensity refers to the wavelength-weighted power emitted by a source in a particular direction. Wavelength-weighted is important here. Because the human eye is … WebThe intensity of illumination at any point from a light source is proportional to the square of the reciprocal of the distance between the point and the light source. Two lights, one having an intensity eight times that of the other, are \( 9 \mathrm{~m} \) apart. On the line between the two light sources, how far from the stronger light is the ...

Web1. The light can cause electrons to be ejected from the metal surface (that’s not so unusual) 2. The energy of these electrons (i.e., their velocity once they leave the metal) does not depend on the light intensity, although the total number of electrons does depend on intensity (rather unusual). 3.
