The correct answer is Christiaan Huygens.

Key Points

• Wave Theory of Light
• In the late 17^th century, scientists were embroiled in a debate about the fundamental nature of light – whether it was a wave or a particle.
• Sir Isaac Newton was a strong advocate of the particle nature of light.
• But, the Dutch physicist, Christiaan Huygens believed that light was made up of waves
• These waves vibrate up and down perpendicular to the direction of the wave propagation and therefore formulated a way of visualizing wave propagation.
• This became known as ‘Huygens’ Principle‘
• This theory was proposed by Huygens in 1678.
• Huygens suggested that each point on the source of light acts as a centre of disturbance from which the waves spread out in all directions,
• The locus of all the particles in a medium vibrating in the same phase is called the wavefront.
• The wavefront due to a point source is spherical and due to a line source is cylindrical. The wavefront corresponding to a parallel beam of light rays is the plane.
• The direction of propagation of the light (ray of light) is perpendicular to the wavefront.
• Each point on a wavefront acts as a source of a new disturbance called secondary wavelets.
• Secondary wavelets spread out as spherical secondary wavefronts with the speed of light.
• The wave theory explains the laws of reflection, refraction, rectilinear propagation, interference, diffraction, as well as dispersion of light.
• The wave theory fails to explain the photoelectric effect of light.
