Pochemu my mozhem videt' ves' disk Luny? Ved' kogda Luna nahoditsya v faze polumesyaca, tol'ko ee chast' osveshena pryamymi luchami Solnca. Otvet – pepel'nyi svet, izvestnyi takzhe kak svet da Vinchi. Ostal'naya chast' obrashennoi k Zemle storony Luny slegka osveshaetsya solnechnym svetom, otrazhennym ot Zemli.
