Question

derive inverse square by formula. law step by step​

Answer 1

Answer:

Formula of Inverse-Square Law:

The inverse-square law formula is articulated as

I∝1/d²  

Where,

distance is d

the intensity of the radiation is I.

At distances d1 and d2, I1 and I2 are intensities of light respectively. Then the Inverse-square law is articulated as:

I1/I2∝d² 2/d² 1

The inverse-square law formula is handy in finding the distance or intensity of any given radiation. The intensity is articulated in Lumen or candela and distance is given in meters. It has widespread applications in problems grounded on the light.
