Physical Science - Chapter Optics - Answer the questions
This paper is the project required for a under graduate student in topic " optics" of subject physical science . The required paper work a reference are provided for the students. Speed of light (c) = 3.0 x 10 exp (8) m/s 1 - Define the following: Ans : Reflection - Reflection is the shift in course of a wavefront at a point of interaction between two unique media so the wavefront gets back to the medium from which it started. Normal models incorporate the reflection of light, sound, and water waves. Refraction - refraction is the shift in direction of a wave passing from one medium and then onto the next or from a steady change in the medium. Refraction of light is the most generally noticed peculiarity, however different waves, for example, sound waves and water waves also experience refraction. 2 - What is the speed of light in glass if you know that the Speed of light in vacuum is (c) = 3.0x108 m/s and the refractive index of...
