Question

According to Huygens’ principle, light is a form of

• A. particle
• B. rays
• C. wave
• D. radiation

Answer 1

The correct option is C

wave

The explanation for the correct option:

1. According to Huygens’ principle, “light travels in the form of a wavefront”.
2. Huygens' principle states that every point on a wave-front is in itself the source of the spherical wavelets. The sum of these wave-fronts forms the wave-front.
3. Huygens' stated that light is a form of a wave that propagates through space like ripples in water or sound in air.
4. Huygens' believed that the ether vibrated in the same direction as the light, and formed a wave itself as it carried the light waves.

Hence, option$\left(C\right)$ is correct.
