WebTaking into account all the above mentioned, the luminous intensity I of a light source (small enough to be considered as a point source) pointing towards the solid angle is given by: I = F/ W -Equation. 3 Where F is the flux measured in lumens. It is clear that the luminous intensity unit is lumen /steradian. WebStart with the equation that relates intensity to displacement amplitude. I = 2π2ρf2v∆s2 Now let's play a little game with the symbols — a game called algebra. Note that many of the symbols in the equation above are squared. Make all of them squared by multiplying the numerator and denominator by 2ρv. Write the numerator as a quantity squared.
