Answer 2

The correct option is (A) Huygens Principle. The diffraction phenomenon is understood by using Huygens Principle.

What is Huygens Principle and how does it word?

• Huygens's principle is otherwise called the Huygens-Fresnel principle.

• Huygens' precept states that each factor on a wave in the front can be a consideration as a supply of secondary waves.
• The phrase interference is used to explain the superposition of waves, while diffraction is interference produced through numerous waves.
• The other options do not suit the question as Fraunhofer is a German research organization, the Uncertainty principle is for the velocity of a particular object that cannot be measured, and Fresnel is a focus light.
