Finally, | | | | | the collect | | | | | settled | | | | | material in | | | | | transparent | | | | | polythene | | | | | cover. | | | | | **Analyze** the | | | | | obtained | | | | | materials and | | | | | describe its | | | | | physical | | | | | properties with | | | | | suitable | | | | | diagram. | | | | | | | | | | **2.** Consider | | | | | a pulsed LASER | | | | | is used in an | | | | | eye surgery of | | | | | the patient at | | | | | a hospital to | | | | | weld a tom | | | | | retina back | | | | | into its | | | | | original place. | | | | | During the | | | | | surgery, the | | | | | LASER is used | | | | | as a pulse for | | | | | the duration of | | | | | 100 ms and its | | | | | power is 2 W. | | | | | Assume that the | | | | | LASER produces | | | | | energy of 5000 | | | | | J and its | | | | | wavelength is | | | | | about 1000 nm. | | | | | Do **Analysis** | | | | | and identify | | | | | which type of | | | | | laser suitable | | | | | for the eye | | | | | surgery and | | | | | state its | | | | | working | | | | | principle. And | | | | | also evaluate | | | | | the following | | | | | parameters: | | | | | | | | | | i\) What is | | | | | the energy of | | | | | each photon? | | | | | | | | | | ii\) How many | | | | | photons | | | | | produced by | | | | | the LASER? | | | | | | | | | | iii\) How long | | | | | its pulse | | | | | length? | | | | | | | | | | **Note:** | | | | | Attach the | | | | | assignment | | | | | material for Q1 | | | | | along with the | | | | | write-up. | | | +-----------------+-----------------+-----------------+-----------------+ **Prepared by: Dr. B.
