Write down the condition for thin film interference. Calculate the position (angular) and the distance between the 3rd and 4th dark lines of the interference pattern on the screen when the slits are spaced 0.450 mm apart and are placed 80.0 cm from the screen. The slits are illuminated with coherent light of wavelength 550nm. Also calculate the distance between the 3rd and 4th dark lines when the entire apparatus was immersed in water. How this separation compares with separation...

Two diffraction gratings, A and B, are located at the same distance from the observation screens. Light with the same wavelength λ is used for each. The separation between adjacent principal maxima for grating A is 2.7 cm, and for grating B it is 3.2 cm. Grating A has 2448 lines per meter. How many lines per meter does grating B have? (Hint: The diffraction angles are small enough that the approximation sin(θ) ~ tan(θ) can be used.)

A chemist identifies compounds by identifying bright lines in their spectra. She does so by heating the compounds until they glow, sending the light through a diffraction grating, and measuring the positions of first-order spectral lines on a detector 15.0 cm behind the grating. Unfortunately, she has lost the card that gives the specifications of the grating. Fortunately, she has a known compound that she can use to calibrate the grating. She heats the known compound, which emits light at...

The spectrum of light from heated up hydrogen gas has only a few wavelengths present. These are known as spectral lines. It includes a red line at 656 nm and a blue-violet line at 434 nm. What are the angular separations between these two spectral lines for all visible orders obtained with a diffraction grating that has 4770 grooves/cm? (In this problem assume that the light is incident normally on the grating.) I'm having trouble with this question as I'm...
