Engineering Math, Period 2, 2 Oct '09
Today the classroom was half in shadow, blue and green fluorescent ceiling tubes spilling a tinted light over Mohinder as he started to speak. "The electromagnetic light spectrum has permeated our science and our lives completely. From the visible region that illuminates our sense of sight up to transmissions of waves of broadcast radio and television or to the shorter heating infra-red or penetrating X-rays."
"Holograms are a static capture of light reflected one from a physical object." He started describing and showing examples.
"The simplest way to create a hologram is with a laser." Mohinder adjusted the machine by his side and a beam of red light flicked on, reflected of a pair of mirrors to hit a light plate. "Together with lenses and mirrors, and of course an object to record." He went into more detail before finishing. "Safety equipment is on the side. You'll need it before creating your own images."
[OCD is up!]
