ELECTROMAGNETICS FINAL PAPER
COMPLETE QUESTIONS AND ANSWERS
EXPERT REVIEWED
●● What are the components of an electromagnetic wave?
Answer: An electric field (E) and a magnetic field (B), both
perpendicular to each other and to the direction of wave propagation.
●● What is random polarization of natural light?
Answer: Natural light has electric and magnetic fields oriented
randomly.
●● What does a polarizing filter do?
Answer: It only allows light of a specific orientation to pass through.
●● What is linear polarization?
Answer: Light waves are organized such that their oscillation occurs
uniformly in one plane.
●● What is circular polarization?
Answer: The electric and magnetic field directions rotate steadily in a
circular motion, either clockwise or counterclockwise.
, ●● How do polarized sunglasses work?
Answer: They reduce glare by utilizing linear polarization.
●● What is optical dichroism?
Answer: A technique that uses polarized light to analyze chirality and
absorbance characteristics of molecules.
●● What is the electromagnetic spectrum?
Answer: It includes all forms of electromagnetic radiation arranged by
frequency and wavelength.
●● What are gamma rays?
Answer: High-energy electromagnetic radiation with wavelengths
smaller than a proton's radius, damaging to cells.
●● What are X-rays used for?
Answer: They have higher frequency than UV rays and can cause health
impacts if not used carefully.
●● What are UV rays and their effects?
Answer: Higher energy/frequency than violet light, capable of causing
DNA damage and skin cancer.
