The correct answer is: B. Law of refraction (Snell’s Law)<\/strong><\/p>\n The law of refraction, also known as Snell’s law, is a formula that describes the relationship between the angle of incidence and the angle of refraction when light passes from one medium to another. The law states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, which is called the refractive index of the second medium relative to the first medium.<\/p>\n The law of reflection is a formula that describes the relationship between the angle of incidence and the angle of reflection when light reflects off of a surface. The law states that the angle of incidence is equal to the angle of reflection.<\/p>\n Millman’s law is a formula that describes the relationship between the voltage, current, and resistance in a circuit. The law states that the voltage across a resistor is equal to the current through the resistor times the resistance of the resistor.<\/p>\n Huygen’s principle is a principle that describes how waves propagate. The principle states that every point on a wavefront can be considered as a source of secondary waves, and the wavefront at any later time is the envelope of these secondary waves.<\/p>\n In conclusion, the law of refraction (Snell’s Law) gives the relationship between the refractive index of the dielectric.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Law of reflection” option2=”Law of refraction (Snell’s Law)” option3=”Millman’s Law” option4=”Huygen’s Law” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[684],"tags":[],"class_list":["post-42814","post","type-post","status-publish","format-standard","hentry","category-optical-communication","no-featured-image-padding"],"yoast_head":"\n
