Read MoreOn 16 May 1960, Ted Maiman used silver coated mirrors, a ruby crystal and a photo flash gun to create the first working laser... Brian Culshaw, author of Introducing Photonics, 2020, explains what makes a laser so useful and introduces a number of the laser's vast applications.
Read More‘A transducer for separating waves on the basis of the frequencies’ or ‘electric filters’ is an interesting but wide study area on account of their ever-increasing areas of applications. Traditionally, filters are classified on the basis of type of passive or active components used which decided their useful frequency range of operation. For example, […]
