Questions: 1. While holding the pencils close to your one eye and looking to the light source you can notice that there is a line perpendicular to the slit. What will happen position of line of the light if you rotate the pencil to vertical? 2. What happen to the blob of light if you squeeze the slit together? 3. Notice that the blob has blue and red edges, which of two colours is closer to the light source? What can you say about their wavelengths?

Question
An experiment about Diffraction:
Kindly answer the 3 questions that follow
Transcribed Image Text:Materials:
1. Two new pencils with eraser
2. Transparent scotch tape
3. Mini flashlight or a candle with matches or a lighter
![Procedure:
1. Light the candle or, if you are using a Mini Maglite, unscrew the top of the flashlight.
2. Wrap one layer of tape around the top of one of the pencils, just below the eraser.
3. Place the light on a stable surface at least one arm's length away from you
4. Hold up the two pencils, side by side, with the erasers at the top. The tape wrapped around one pencil
should keep the pencils slightly apart, forming a thin slit between them, just below the tape. Hold both
pencils close to one eye (about 1 inch [2.5 cm] away) and look at the light source through the slit between
the pencils. Squeeze the pencils together, making the slit smaller.
Questions:
1. While holding the pencils close to your one eye and looking to the light source you can notice that there
is a line perpendicular to the slit. What will happen position of line of the light if you rotate the pencil to
vertical?
2. What happen to the blob of light if you squeeze the slit together?
3. Notice that the blob has blue and red edges, which of two colours is closer to the light source? What
can you say about their wavelengths?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F73d5f9c2-3a2b-4195-946e-5550688b9b9a%2F9b17d6fd-f17b-49fa-b47c-19cb5a89807b%2Fberdudb_processed.jpeg&w=3840&q=75)
