A quarter has a profile of George Washington with his nose pointing left and the word LIBERTY above his head. In a class demonstration, we reflected bright light off of an up-side-down quarter and directed the reflected light through a converging lens on to the opposite wall.

What appeared on the wall?

       a. A real image was formed with George's head upright, his
           nose points to the right and the first two letters
           of the word above his head read YT, left to right.
        b. A virtual image was formed with George's head upright, 
           his nose points to the right and the first two 
           letters of the word above his head read YT, left to right.
        c. A real image is formed with George's head upright, his 
           nose points to the left, and the word LIBERTY is seen above.
        d. A up-side-down image of George is formed with the word
           LIBERTY up-side-down too.


 26.    We then intercepted the light after it emerged from the lens
        and reflected it to the wall on the other side of the room.

Answer #1

when the upside down coin's image is formed form a converging lens on a screen

then the image is real and relatively inverted

hence the resultant image is upright

also, when the coin is downwards, the nose points to right

so in the image, the nose points to left

hence

c. a real image was formed, with head upright, nose points to the left, and word libery is seen on the top

26. when the light was reflected too

there will be lateral inversion as well

hence

a. a real image , upright, nose to right, and letters start from YT
