Show HOW TO SEE FOUR MOONS experiment can be tried with a mir on a cloudless night A pretty experiment can be made with a hand mirror any night when there Is a full moon hold the mir so that the moons image will be been in it and you will be surprised to see tour moons instead of one one moon will be very bright but the other three will be in a straight line and quite dull one dull image on one side of the bright moon and the other two on the other side turn the mir around slowly still holding its face to the moon and the reflections will seem to revolve around a corn mon center you can make the same experiment with any one 0 the very bright stars such as sirius venus or jupiter but with these there will be three images instead of tour as the number seen depends on the of the object the explanation 1 simple there are surfaces in a mirror one in front and the othe where the quick silver Is the brightest reflection comes from the object itself the oth ers are what Is known as secondary images reflected from the front to the back of the mirror and thence to the eye the magic mirror never falls to excite a good deal of wonder and Is an interesting experiment as well |
