Is my math right? I can't figure out what I need to put in the table above. Help please! Refraction of Light Data Table: W n1 01 02 0 1 e', sin sin 2 n2 % Diff dmeas Idcalc % Diff | 7.4 cm 1 50 26 50 26 2.1 cm Questions: 1) What is the speed of light in Water and BK-7 glass? V=3x10^8/1.517 V= 1.978x10^8 m/s 2) A light ray in air strikes water at an angle of...
Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
I don't understand Question 5-9 Any information on how to answer these? The speed of light depends on the medium through which it travels, and it is generally slower in the denser media. Fermat's principle in optics asserts that light travels from one point to another along a path for which the time of travel is minimum. In a uniform medium, where the speed of light remains constant, "shortest time" means "shortest path", and the ray of light follows a...
