    • study such a phenomenon quite exactly. Suppose I have two mirrors and
    • get pictures by means of the one mirror and also pictures by means of
    • the other mirror. Such is the distribution you are to assume; I draw
    • mirrors, set at a very small angle to one another, — here is a
    • light strike here, with the help of this mirror I can illumine this
    • region. Now I have here a second mirror, by which the light is
    • reflected from here below (from the second mirror) on to the screen,
    • still falls into the upper part. The inclination of the two mirrors
    • upper mirror and by reflection from the lower. It will then be as
    • bombards the first mirror, hurling its little cannon-balls in this
    • direction. After recoiling from the mirror they reach the screen and

    • much lighter on the screen when there are two mirrors than when there
    • is only one. Therefore if I remove the second mirror the screen will
    • surely be less illumined by reflected light than when the two mirrors
