How do fiber optics work?
Everything that you say over the phone or send over the Internet at some point travels as pulses of light through strands of glass called fiber optic cables. Collaborate with a team to research the field of fiber optics. Create a multimedia presentation that explains the role of total internal reflection in fiber optic transmissions. Review and comment on other presentations by your classmates.
