- Estimate the linear separation (in kilometers) of two objects at a distance of 1.9 × 10° km that can just be resolved by an observer on Earth (a) using the naked eye and (b) using a telescope with a 7.4-m diameter mirror. Use the following data: diameter of pupil = 5.0 mm; wavelength of light = 550 nm. %3D (a) Number i 2.5E8 Units km (b) Number i 1.7E5 Units kmOur eyes are typically 6 cm apart. Suppose you are somewhat unique, and yours are 3.50 cm apart. You see an object jump from side to side by 0.75 degree as you blink back and forth between your eyes. How far away is the object?Suppose you are looking down at a highway from a jetliner flying at an altitude of 6.0 km. How far apart must two cars be if you are able to distinguish them? Assume that =550 nm and that the diameter of your pupils is 4.0 mm.

- 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.

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.…

"How do you know it was the suspect?" you ask. "I clearly saw the 'MOM' that is tattooed on his upper arm." "You're sure it was that particular tattoo and not some other tattoo?" "Yes, I'm sure," The witness replies. The suspect's tattoo has letters that are 6cm tall. Is the witness credible, or might he be framing the suspect? Justify your response and any estimates you might make.
