Given a diffraction grating of red light at 650nm at an angle of 37.5o how many lines per cm does the grating have?
The Hubble Space Telescope (HST) orbits Earth at an altitude of 613 km. It has an objective mirror that is 2.40 m in diameter. If the HST were to look down on Earth's surface (rather than up at the stars), what is the minimum separation of two objects that could be resolved using 549 nm light? [IVote: The HST is used only for astronomical work, but a (classified) number of similar telescopes are in orbit for spy purposes.]

The limit to the eye's acuity is actually related to diffraction by the pupil. What is the angle between two just‑resolvable points of light for a 6.25 mm diameter pupil, assuming the average wavelength of 539 nm? angle between two points of light: ° Take the result to be the practical limit for the eye.

A beam of light of wavelength 691 nm passes through two closely spaced glass plates, as shown in the figure.For what minimum nonzero value of the plate separation d will the transmitted light be bright? (This arrangement is often used to measure the wavelength of light and is called a Fabry-Perot interferometer.)
a) At what angle is the first minimum for 550-nm light falling on a single slit of width 1.00 um? When i solve the question, there is no way i get the answer to be 33.4 deg. rather i get the sin-1 (0.55) = 0.58. IS the final answer wrong in the bartley and the test book or am i wrong?
