Ever wondered what law perspective follows?

  1. Jun 23, 2005 #1
    Anyone ever wondered what law pespective follows? If there is one... I mean a relationship between apparent height and real height over a distance. I was going to try an experiement if I ever get round to it. I'll be disapointed if its just another inverse square law :biggrin:

    I just did a quick exp then and I think its a linear relationship.

    I tried it with the lights at work and it didn't seem to be I'll try again lol

    Well i held a phone x distance awy nad held a ruler to my eye and measured the apparent height, and then i moved the phone 2x away and the height increased lineraly (i think!)

    Hmm found a ruler. I seem to get it as it halfs with doubling the distance. So is that 1/d? Can't think tonight.

    Yep - linear relationship

    Apparent height = k/distance

    where k is a constant
