Light emitted by element X passes through a diffraction grating that has 1200 slits/mm. The interference pattern is observed on a screen 80.0 cm behind the grating. First-order maxima are observed at distances of 56.4 cm , 67.1 cm ,and 93.5 cm from the central maximum. What are the wavelengths of light emitted by element X?
What angular separation is obtained after two spectral lines of 550.0 nm and 632.0 nm areobserved with a diffraction grating that is 4000 groves/mm?.
In a modified Young's double slit experiment, a
monochromatic uniform and parallel beam of light of
wavelength 6000 A and intensity (10/) Wm2 is incident
normally on two apertures A and B of radii 0.001 m and
0.002 m respectively. A perfectly transparent film of thickness
2000 A and refractive index 1.5 for the wavelength of 6000A is
placed in front of aperture A (see figure). Calculate the power
(in W) received at the focal spot F of the lens. The lens is
symmetrically placed with respect to the apertures. Assume
that 10% of the power received by each aperture goes in the
original direction and is brought to the focal spot.

- Coherent light rays of wavelength strike a pair of slits separated by distance d at an angle 1, with respect to the normal to the plane containing the slits as shown in Figure P27.14. The rays leaving the slits make an angle 2 with respect to the normal, and an interference maximum is formed by those rays on a screen that is a great distance from the slits. Show that the angle 2 is given by 2=sin1(sin1md) where m is an integer.arrow_forwardA Fraunhofer diffraction pattern is produced on a screen located 1.00 m from a single slit.

- In an interference experiment using a monochromatic source emitting light of wavelength å, the fringes are produced by two long, narrow slits separated by a distance d. The fringes are formed on a screen which is situated at a distance D >> d. Write down an expression for the fringe width w. Please use Il * II for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. Use "lambda" (without the quotes) for å in the equation box. For example, use d*lambda for d2. Please use the "Display response" button to check you entered the answer you expect.arrow_forwardLight with wavelength å passes through a narrow slit of width w and is seen on a screen which is located at a distance D in front of the slit.
