What type of waves did Fresnel propose light waves to be?
Longitudinal waves
Transverse waves
Mechanical waves
Electromagnetic waves
Answer
Fresnel proposed that light waves are purely transverse, which helped him explain the nature of polarization, chromatic polarization, and the transmission and reflection coefficients at the interface between two transparent isotropic media.
