The illuminance On a surface is six lux and the surface is 4 meters from the light source what is the intensity of the source

Respuesta :

Answer : 96 candelas

Explanation : Luminous intensity is a quantity of light that is emitted by a light source with a solid angle in a particular direction.

We know the formula of luminous intensity

Luminous intensity = illuminance x distance from light source

[tex]L_{v} = E_{v}\times d^{2}[/tex]

[tex]L_{v} = 6\times 16\ candelas[/tex]

[tex]L_{v} = 96\ candelas[/tex]

So, the intensity of the source will be 96 candelas.
