The students of this Science City created a Guinness World Record by assembling the largest spectroscope in just 45 minutes, during the fifth India International Science Festival (IISF) 2019, with the participation of over 1,598 students, the Department of Science and Technology said here.
Astronomers use spectroscopes to know the details like temperature and chemical composition of celestial objects, which are hundreds or millions of light years away from the earth.
The students on Tuesday made a small personal model of advanced spectroscopes using a box made of cardboard that has a very narrow window used to channel light into the spectroscope and a piece of a Compact Disc, used to split the light by a process called diffraction. Thousands of visitors witnessed this wonderful advanced spectroscopes at the ‘Science Expo’ at Science Centre at Kolkata. This attempt is dedicated to eminent astrophysicist Meghnad Saha and renowned physicist Chandrasekhara Venkata Raman.
On Wednesday, the largest electronics lesson and assembly of optical media communication units at a single location will be attempted with the participation of over 1,000 students. Communication link set up through Infrared signals – Wireless infrared communications refers to the use of free-space propagation of light waves in the near infrared band as a transmission medium for communication.
This attempt is dedicated to Dr Raman and distinguished physicist Satyendra Nath Bose. The host city of the fifth IISF-2019 is home to renowned scientific institutions that have been the workplace of pioneering scientists, who gave shape to science in India. IISF is the largest science festival in the world. The theme for this year’s festival is RISEN India – Research, Innovation and Science Empowering the Nation.
