Find the wavelength if 550 bright fringes 0.150mm. of light used in a Michelson interferometer go by a fixed point when the mirror moves

Light passes through two parallel slits separated by a distance of 1.98 μm. Calculate the wavelength of light in units of nm if the third-order maximum is at an angle of 60.0 degrees.

How many dark fringes will be produced on either side of the central maximum if light (λλ = 699 nm) is incident on a single slit that is 4.84 × 10-6 m wide?

What is the distance, in meters, between two parallel plates when a ray with a wavelength of 490 nm is placed through the slit and the third maximum was at a 0.52°?

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 2.75 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. What is the greatest possible distance a car can be from a person if he or she can resolve its two headlights, given they are 1.40 m apart? greatest distance at which headlights can be distinguished: m What is the distance between two just-resolvable points held at an arm's length (0.900 m) from a person's eye? distance between two points 0.900 m from a person's eye: m
