Physics · Wave optics: wavefront and Huygens' Principle, laws of reflection and refraction using Huygens principle
Choose the correct option about light.
Choose the correct option about light.
- A. Light requires a material medium to travel from one place to another
- B. Light does not require a material medium to propagate
- C. Light has mass but it is negligible
- D. Light waves are longitudinal wave
Step-by-step solution
Light is an electromagnetic wave, which can travel through a vacuum. Therefore, it does not need a material medium. Option A is incorrect because light can travel without a medium. Option C is false because light has no rest mass. Option D is false because light waves are transverse, not longitudinal.
