1) What is the highest order dark fringe, m,m, that is found in the diffraction pattern for light that has a wavelength of 621 nm and is incident on a single slit that is 1470 nm?

2) You stand on a straight desert road at night and observe a vehicle approaching. This vehicle is equipped with two small headlights that are 0.637 m apart. At what distance, in kilometers, are you marginally able to discern that there are two headlights rather than a single light source? Take the wavelength of the light to be 555 nm and your pupil diameter to be 5.17 mm.

Solutions

Expert Solution

1. More information on how far is the slit located from the screen is required.

2. Let L: distance between the two headlights, D:pupil's diameter

The angular resolution is given by,

where R : distance of the vehicle.

A diffraction grating has a chromatic resolving power of 20,000 in first order (m = 1). (i) What is the number of slits in the grating? (ii) This grating is used to analyze the spectrum of light coming from stars, in the third order (m = 3). The analysis involves resolving wavelengths that are close the spectral wavelength of some element (500.0 nm). What is the range of wavelengths you cannot distinguish from the said spectral wavelength? Hint: Chromatic resolving...
