A mixture of violet light (wavelength of 410 nm) and red light (wavelength of 660 nm) falls on a diffraction grating that contains 1 x 104 lines/cm. For each wavelength, find the angle that corresponds to the first-order maxima. Draw a sketch to support your answer. (violet 24 degrees; red 41 degrees)

Problem 10:   Consider a diffraction grating through which monochromatic light (of unknown wavelength) has a first-order maximum at 22°. At what angle, in degrees, does the diffraction grating produce a second-order maximum for the same light?

The Rayleigh criterion provides a convenient way to describe the theoretical resolution (e.g. an ability to distinguish two bright objects ) of an optical system. The criterion states that two small bright sources of light can be resolved if the first diffraction minimum of the image of one source point just coincides with of further apart then the first maximum of another (see figure below). A converging lens, 34.2 mm in diameter, is used to form images of distant objects. Considering the diffraction by the lens, what angular separation must two distant point objects have in order to satisfy Rayleigh's criterion? Assume that the wavelength of the light from the distant objects is 431 nm. Provide your answer in millidegrees (mdeg). Answer: Choose... +

A mixture of blue light (wavelength of 400 nm) and red light (wavelength of 630 nm)falls on a (transmission) diffraction grating that contains 2 x 103 lines/cm. What is theangular separation of.the two colors at the first-order maxima? Make a simple sketch tosupport your answer.(I know the answers are 2.65 degrees = 0.046 radians. I just want to see the process and the sketch)

slit of width 0.46 mm is illuminated with light of wavelength 534 nm, and a screen is placed 114 cm in front of the slit. Find the widths of the first and second maxima on each side of the central maximum. w1 = mm (1st maxima) w2 = mm (2nd maxima)

A diffraction grating with n = 2.5E-05 lines/nm is used to separate two colors of light. The angle between their first maxima is Δθ ≡ θ1 - θ2 = 0.44 degrees, and the first light has wavelength λ1 = 618 nm.  Part (a)  Find θ1 using n and λ1 in radians.   Part (b)  Find θ2 in radians.  Part (c)  Find the value of the wavelength of the second color λ2 in nm.
