Question

Who first proposed that light was wave-like in character?

• A. Huygens
• B. Newton
• C. Young
• D. Maxwell

Answer 1

The correct option is A

Huygens

1. Christian Huygens (1629-1695), a Dutch physicist, established the Huygens' principle and the wave theory of light in 1678.
2. Christian Huygens proposed in 1678 that light is made up of waves that vibrate up and down perpendicular to the direction of light flow, resulting in a means of visualizing wave propagation.
3. Huygens assumed that ether vibrated in the same direction as the light, resulting in the formation of a wave.

Hence, the correct answer is option A i.e. Huygens.
