Refraction and Diffraction Lessons

​24-26

​When light hits a boundery (change of medium), some light will reflect but the rest refracts by slowing down, but why…

In a rainbow what wavelength of visible EMR tends to commonly be on the outer arch, as it refracts the least? (red=700nm where blue=400nm)

Based on this diagram let's calculate the index of refraction for the glass. (to the nearest hundredth)

​Now, Consider if the same object were placed in front of a convex lens with a real focal length of 12.3cm.
What would the properties of the image be? (d_i , h_i , etc...)

​Recall from this mirror question that the d_i is negative confirming the virtual nature of the image, and that the focal length would also be negative
(which is always true for diverging mirrors).
