Question
In Huygens' theory, light waves
✓
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.
