Answer:
To make a pinhole camera you will need the following materials:
· A box, which will serve as a "camera". It can be any type of box, but you should be careful to close it well so that the light does not enter.
· An aluminum can.
· Scissors or some other cutting tool.
· A pushpin or pin.
· Black insulating tape.
· Photographic paper.
1. The first thing you will have to do is a hole in the box. You can do it with a circular or rectangular shape. In addition, it is advisable to paint or line the inside of your black box so that the light does not strain inside and get better results in your photograph.
2. Cut a piece of aluminum from the can. It will be in that portion of metal where you will make the hole through which the image of your photograph will later enter.
3. With the pin make a hole in the piece of metal you just cut. This hole is called a pinhole and is the hole through which light will enter your camera. In English pinhole cameras are called pinhole through this hole made with a pin.
The smaller the hole the sharper the image will be, but don't make it too small, as it could cause the opposite effect.
4. When you have your piece of metal with the created pin, stick it to the box with black duct tape. Use a piece of black tape to cover the pinhole, so that no light enters while you don't want the image to be captured.
5. Finally, place the photo paper inside the box. Remember to do this last step in a dark room, since otherwise, the light would damage the paper and would not serve to take pictures.
Answer:
The sound level of 41 singers is approximately 79.52 dB.
Explanation:
As the sound level is given as 63.4 dB
The Intensity to Sound level relation is given as
Here β is given as 63.4 dB
I is to be calculated for 1 singer
I_o is constant as 10⁻¹²
So the equation is given as
Now as there are 41 singers so their I is given as
Now the value of sound level is given as
