White light is made of all colours of the visible spectrum which
has a wavelength range of approximately 380 – 750 nm (violet to
red). White light is incident on a diffraction grating that has 90
lines/mm. What is the width of the 1st order rainbow
band that appears in the diffraction pattern if the screen is 1.60
m away? Express your answer in mm and round to 2 decimal
places.

The Experiment. Does light environment have an influence on the development of color vision? The data are measurements on the relative abilities of Bluefin killifish from two wild populations to detect short-wavelength light (blue light in our own visible color spectrum). One population was a swamp, whose tea-colored water filters out blue wavelength, whereas the other population was from a clearwater spring. Fish were crossed and raised in the lab under two light conditions simulating those in the wild: clear...

8. Visible light has wavelengths between about 1 = 400nm on the violet end of the spectrum to about l = 700nm on the red end. An anti-reflective coating with index ne = 1.2 forms a thin film on the surface of a glass lens with index n, = 1.5. (a) For a wavelength in middle of the visible-wavelength range (which appears green), find the minimum thickness of the coating for dark reflections of light entering the lens from the...

this kinda of a long question, but all parts are connected. so, please explain ! The first quantitative description of the hydrogen spectrum was given by Johann Balmer, a Swiss school teacher, in 1885. By trial and error, he found that the correct wavelength ? of each line observed in the hydrogen spectrum was given by 1?=R(122?1n2), where R is a constant, later called the Rydberg constant, and n may have the integer values 3, 4, 5, ....
