MCQ
In Huygens' theory, light waves
  • A
    are transverse waves and require no medium to travel.
  • B
    are longitudinal waves and require a medium to travel.
  • C
    are transverse waves and require a medium to travel.
  • D
    are longitudinal waves and require no medium to travel.

Answer

(b) are longitudinal waves and require a medium to travel.
Explanation: According to Huygens, light waves are longitudinal waves and require a material medium to travel. For this reason Huygens assumed the existence of a hypothetical medium called luminiferous aether.
