Build Your Own Pinhole Camera
Next thing you have to do is to build a top piece for your torch. Use the black cardboard for this. You need another disc which fits on the front of your torch. The diameter of the cardboard disc must be the same as the diameter of your torch. When you have cut out the disc, use the needle or pin to pierce little holes in this disc. Use tape to stick this top piece onto the front of your torch. Later you can also create several other top pieces with your name or any pattern you like, but for now just use the top piece with the number one.
Now, all you have to do is darken your room. Make sure there practically no source of light. The experiment with your pinhole camera will only work well in a really dark room.
When you look at the number one, how does the image on the transparent paper look like? b) The number one stands upside down and left and right are reversed compared to the top piece on the torch. c) The number one is the same in height and left and right is the same as on the top piece on the torch. d) The number one is reversed in height but left and right is the same as on the top piece on the torch. |
