When dots are placed on a page from a laser printer, they must be close enough so that you do not see the individual dots of ink. To do this, the separation of the dots must be less than Raleigh's criterion. Take the pupil of the eye to be 3.4 mm and the distance from the paper to the eye of 46 cm; find the maximum separation (in cm) of two dots such that they cannot be resolved. How many dots per inch (dpi) does this correspond to?

When dots are placed on a page from a laser printer, they must be close enough so that you do not see the individual dots of ink. To do this, the separation of the dots must be less than Raleigh’s criterion. Take the pupil of the eye to be 3.0 mm and the distance from the paper to the eye of 35 cm; find the minimum separation of two dots such that they cannot be resolved. How many dots per inch (dpi) does this correspond to?
In Equation 4.4, the parameter looks like an angle but is not an angle that you can measure with a protractor in the physical world. Explain what represents.

What is the smallest thing we can see? O smallest object that we can process with our eyes is limited to the size of the photoreceptor cells in the retina. In order for us to to distinguish any detail in an object, its image cannot be smaller cannot be smaller than a single retinal cell. Although the size depends on the type of cell (cone or rod), a diameter of of a few microns (mm) is common near the center of the eye. We should model the eye as a sphere 2.50 cm in diameter with a single slender lens in front and the retina behind, with photoreceptor cells 5.0 mm in diameter. (a) What is the smallest object object that you can perceive at a point near 25 cm? What angle is subtended by this object in the eye? Express your answer in units of minutes (1° 60 min) and compare it with the typical experimental value of about 1.0 min. (Note: there are other limitations, but we will ignore them here).

A physicist is hired to do some decorating at a celebration. The client is very keen on including some lighting effects, and in particular wants to have 365 stripes of yellow light (581.0 nm) evenly distributed on a 5.00 m Plexiglas board.a) Draw a labelled sketch of the display installation using an air wedge.b) Calculate the number of pieces of paper (each 1/10th of a millimeter) the physicist would need to insert at one end of the boards to make this happen.
Problem 3. A 1mm filament produces a 1mm × 1mm electron beam incident on an anode disk with anode angle = 13°.The center of the focal spot is 1 m away from a detector which is centered at the center of the focal spot on the anode disk and is 50 cm wide. Determine the effective focal spot dimensions on the disk and the dimensions of the focal spot in the center of the detector, at the far anode edge of the detector, and at the far cathode edge of the detector (see figure below which is definitely not to scale). 1 m աալ 0 40 cm
Hi, can you please make this one clear. The spacing makes me confused. Thank you!
Often in optics scientists take advantage of effects that require very high intensity light. To get the desired effect a scientist uses a laser with power P = 0.0065 W to reach an intensity of I = 170 W/cm2 by focusing it through a lens of focal length f = 0.11 m. The beam has a radius of r = 0.0011m when it enters the lens. Randomized VariablesP = 0.0065 WI = 170 W/cm2f = 0.11 mr = 0.0011 Part (a) Express the radius of the beam, rp, at the point where it reaches the desired intensity in terms of the given quantities. (In other words, what radius does the beam have to have after passing through the lens in order to have the desired intensity?) Part (b) Give an expression for the tangent of the angle that the edge of the beam exits the lens with with respect to the normal to the lens surface, in terms of r and f? Part (c) Express the distance, D, between the lens's focal point and the illuminated object using tan(α) and rp. Part (d) Find the distance, D, in centimeters.…
