What is the separation between two slits for which 610-nm orange light has its first maximum at an angle of30.0掳?

Short Answer

Expert verified

The separation between two slits is1.22'10-8m.

Step by step solution

01

Given data

The wavelength of the orange light is 位=610nm10-掳m1nm=6.1脳10-7m

The angle for the first maximum is 30.0掳

02

Finding the separation between two slits

A formula for the angle of the first-order maximum can be expressed as,

dsin胃=位鈥︹赌︹赌︹赌︹赌︹赌︹赌︹赌︹赌︹赌�.(1)

Substituting the given data in equation (1), we get,

d脳sin30.0掳=6.1脳107md=6.1脳107m0.5d=1.22脳10-6m

Thus, the separation between two slits is 1.22'10-6m.

What is the spacing between structures in a feather that acts as a reflection grating, given that they produce a first-order maximum for 525鈥�nmlight at a 30.0掳angle?

No light passes through two perfect polarizing filters with perpendicular axes. However, if a third polarizing filter is placed between the original two, some light can pass. Why is this? Under what circumstances does most of the light pass?

Consider a spectrometer based on a diffraction grating. Construct a problem in which you calculate the distance between two wavelengths of electromagnetic radiation in your spectrometer. Among the things to be considered are the wavelengths you wish to be able to distinguish, the number of lines per meter on the diffraction grating, and the distance from the grating to the screen or detector. Discuss the practicality of the device in terms of being able to discern between wavelengths of interest.

An inventor notices that a soap bubble is dark at its thinnest and realizes that destructive interference is taking place for all wavelengths. How could she use this knowledge to make a non-reflective coating for lenses that is effective at all wavelengths? That is, what limits would there be on the index of refraction and thickness of the coating? How might this be impractical?

(a) Find the maximum number of lines per centimeter a diffraction grating can have and produce a maximum for the smallest wavelength of visible light. (b) Would such a grating be useful for ultraviolet spectra? (c) For infrared spectra?
