PHYS 102 1st Edition Lecture 25Outline of Last Lecture I. Solving for WavelengthOutline of Current Lecture II. EM Waves III. Refractive Index Current LectureII. EM WavesA. Which of these do not ordinarily emit electromagnetic waves? 1. The Sun 2. Lava from a volcano 3. Red-hot coals 4. This page 5. … but all continually emit EM waves. 6. is the correct answer. III. Refractive Index A. Angle of incidence = angle of reflection B. Snell’s Law: n1 sin 1 = n2 sin 2 ; Where n is the refractive index, 1 is the angle of incidence, and 2 is the angle of refraction. N is the resistance to EM waves. C. n = C/V ; where C is the speed of light in vacuum/ air (all EM waves) and v is the speedof light in the material; V is less than C, depends on the material These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Unit of n : = C/V = speed/speed = (m/s)/(m/s) so no units Air & vacuum: n = 1 Know this!! Not given on
