Light of wavelength 6200a falls on a metal
WebThe wavelength of light in the visible region is about 390 nm for violet colour, about 550 nm (average wavelength) for yellow-green colour and about 760 nm for red colour. ... Therefore, metal 'Q' has smaller wavelength. (ii) As we know, E = hv 0 Hence, metal 'P' has smaller kinetc energy. ... Light of wavelength 2000 A falls on an aluminium ... Websecond-order spectrum between red light of wavelength 7:0×10−7m and blue light of wavelength 4:5×10−7m. Solution: Using Eq.35-13, we find the second order angles for the maximum and minimum wavelength, where the slit separation distance is the inverse of the number of lines per cm. Subtracting these two angles gives the angular width.
