MY NOTES ASK YOUR TEACHER Using filters, a photographer has created a beam of light consisting of three wavelengths: 400 nm (violet), 500 nm (green), and 650 nm (red). He aims the beam so that it passes through air and then enters a block of crown glass. The beam enters the glass at an incidence angle of , = 26.60. The glass block has the following indices of refraction for the respective wavelengths in the light beam. wavelength (nm) 400 500 650 index of refraction ano 1.53 50 - 1.52 06501.51 (a) Upon entering the glass, are all three wavelengths refracted equally, or is one bent more than the others? O 400 nm light is bent the most 500 nm light is bent the most O 650 nm light is bent the most O all colors are refracted alike (b) What are the respective angles of refraction (in degrees) for the three wavelengths? (Enter each value to at least two decimal places.) (1) #400 mm (ii) 500 nim (ill) 8 650 nm Need Help? Read It
