What are two wavelength-dispersing elements in monochromator? Which is better and why?

Expert Solution

The two wavelength dispersing elements in monochromator are prism and grating.

A monochromator is an optical device that transmits a desired narrow band of wavelengths of light from a wider range in the input. It used the phenomenon of optical dispersion in a prism, or diffraction of a grating.

The dispersion is a parameter which characterizes as the width of the band of colors per unit of slit width. This factor is constant for a grating, but varies with wavelength for a prism. This shows that the grating can be used for a wide range of wavelength with equal dispersion; however prism is ineffective with lower wavelength. Also, separation due to grating is higher than the prism. Grating is used in the reflective mode, while prism is used in the transmitive mode.

The material of the prism, i.e. glass, is clear to visible light, but it absorbs and blocks light in the infrared and ultraviolet part of the spectrum. However, grating doesn't suffer with this issue.

Write a C++ function which will search for TWO elements. The two elements must be right next to each other, contiguously. The prototype of the function should be: bool search_adjacent_elements(int const *x, size_t n, int target1, target2); It will return true if target1 and target2 exist in the array x somewhere, with target1 immediately to the left of target2. For example: int x[] = { 3, 5, 10, 14, 19, 25, 45, 60 }; cout << search_adjacent_elements(x, sizeof x /...
