Instrument for measuring light intensity

Nettet5. feb. 2024 · We can write this as a formula, then rearrange it to solve for I 2, or the relative intensity of the second light source: I 1 /d 12 = I 2 /d 22. I 2 = I 1 (d 22 /d 12) Since we're only measuring the relative intensity, or how they compare, we can just say I 1 = 1. This will make our formula simple: I 2 = d 22 /d 12.
