To Explain:
Huygens' principle, and why is it necessary to understand Snell's law of refraction.
Expert Solution & Answer
Explanation of Solution
Introduction:
It is given to have an idea about Huygens' principle and Snell's law of refraction.
Christiaan Huygens proposed that every point along the front of a wave be treated as many separate sources of tiny "wavelets" that move at the speed of the wave. This is essential to see how light moves from one medium to a different medium and allows you to predict the bending that occurs in Snell's law. This is why Huygens' principle is necessary to understand Snell's law of refraction.Conclusion:
Huygens' principle and why is it necessary to understand Snell's law of refraction is explained
