Explain the experimental method to determine the wavelength of spectral line using diffraction grating.
What is the highest order spectrum which can be seen with monochromatic light of wavelength 6000 Ao by means of a diffraction grating with 5000 lines/cm?
What is diffraction grating? What is the advantage of increasing the number of lines in the grating?
Discuss the Fraunhoffer diffraction at single slit and obtain the condition for minima.
In plane transmission grating the angle of diffraction for second order principal maxima for wavelength 5 x 10-5 is 35o. Calculate number of lines/cm for this diffraction grating.
