![]() Light of wavelength 550 nm falls normally on a slit of width 22.0×10−5cm…?.Unpolarized light of intensity I is incident on a system of two polarizers, A followed by B…?.Diameter of the objective lens of a telescope is 250cm.In an interference experiment, the ratio of amplitudes of coherent waves is…?.Therefore, the wavelength will be 0.5 x 10 -6 m. If there are 1000 lines per millimeter of grating length, what will the wavelength of the light be? Light is diffracted at 30 o by a diffraction grating. Therefore, the wavelength will be 1.7 x 10 -7 m. Using the formula λn = dSinθ n, (by setting n to 1) If there are 2000 lines per millimeter of grating length, what will the wavelength of the light be? ![]() Light is diffracted at 20 o by a diffraction grating. Thus, the Grating element, d = Grating length/Line count. Note: A grating element is also the distance between two successive slits (lines) of the grating.
