Question

A grating is used to resolve the sodium D lines (589.0nm and 589.6nm) in the first order. How
many rulings (slits) are needed?
If the focal length of the focusing lens is 20cm, and the total width of the grating is 2cm, what is
the linear separation at the focal plane between the two D lines?

Estimate the linear separation (in kilometers) of two objects at a distance of 1.4 x 106 km that can just be resolved by an observer on Earth (a) using the naked eye and (b) using a telescope with a 5.4-m diameter mirror. Use the following data: diameter of pupil = 5.0 mm; wavelength of light = 550 nm. (a) Number i Units (b) Number i Units
A reflecting telescope has a main mirror with fM = 620 mm. If an eyepiece with a magnification of 15 is used, what is the total magnification of the telescope? Assume the near-point distance of the eye is 25 cm.
You observe, at normal incidence, light of wavelength 483 nm reflected off the (air) interface between a plano-convex lens (curved side down) touching a flat piece of glass. You see a dark central spot surrounded by rings of darkness. The smallest ring has radius 187 μm. If the lens is made of glass with refractive index 1.532, what is the focal length of the lens in cm?
An astronomical telescope has an objective with focallength 75 cm and a +25 D eyepiece. What is the totalmagnification?
What is the smallest possible feature size that can be resolved by using a 193-nm optical source and the highest possible NA that can be obtained by a lens when exposing the image in air? Note that NA can be determined by the equation NA = n∙sin(θ) where n is the index of refraction of the medium in which the lens is working (air in this instance) and θ is the maximal half-angle of the cone of light that can enter or exit the lens and has a maximum possible value of 90˚ for a very large lens.

Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. 62.0 mm In the figure, a double-glazed window consists of two identical of glass (ng panes 1.54), each yg thick, separated by an air gap of ya = 49.6 mm. Use na = 1.00 for the index of refraction of air. = If light incident on the glass makes an angle of = 40.00° with respect to the glass, find the shift in path Ax as the light enters the room. Ax = 42.36 Incorrect glass air glass mm
