Kolkata: The Guinness World Records for the largest astrophysics lesson (45 minutes) and assembly of spectroscopes was successfully achieved at the Science City, Kolkata on the first day of India International Science Festival (IISF) 2019 on Tuesday with the participation of over 1,598 students.
Astronomers use spectroscopes to know details like temperature, chemical composition, etc. of celestial objects hundreds or millions of light years away from us.
A small personal model of advanced spectroscopes can easily be made by anyone using a box made of cardboard that has a very narrow window used to channel light into the spectroscope.
A piece of a Compact Disc is used to split the light by a process called diffraction. This attempt is dedicated to Meghnad Saha and C. V. Raman.
