Unit IV. Light as an Electromagnetic Wave
Lesson 5
Nature of Light
,Timeline
Christiaan Huygens proposed a wave property of
1678 light. He defined that the light is vibrating up and
down, perpendicular to the direction of the
propagation of light.
James Clark Maxwell predicted the existence of
1873
electromagnetic wave.
Heinrich Hertz provided experimental confirmation
1887 of Maxwell’s theory, and showed conclusively that
light is an electromagnetic wave.
,Electromagnetic Waves
• waves that can travel through a
vacuum
• are capable of transporting
energy through a vacuum,
unlike mechanical waves
• produced by a vibrating electric
charge and as such, they
consist of both an electric and a
magnetic component Source: kaiserscience.wordpress.com
