Question

The resolution of the eye is ultimately limited by the pupil diameter. What is the smallest diameter spot the eye can produce on the retina if the pupil diameter is 3.80 mm? Assume light with a wavelength of ? = 550 nm. (Note: The distance from the pupil to the retina is 25.4 mm. In addition, the space between the pupil and the retina is filled with a fluid whose index of refraction is n = 1.336.) Hint: The size of the spot is twice the distance from the main axis to the first minimum.

Answer #1

Calculate the limiting angle of resolution for the eye, assuming
a pupil diameter of 1.75 mm, a wavelength of 520 nm in
air, and an index of refraction for the eye of 1.33.
____ rad
(b) What is the maximum distance from the eye at which two points
separated by 14.00 cm could be resolved?
____m

calculate the limiting angle of resolution for the eye, assuming
a pupil diameter of 2 mm, a wavelength of 500 nm in air, and an
index of refraction for the eye equal to 1.33. calculate the
minimum separation d between two points that the eye can
distinguish, if the points are at a distance L = 25 cm from the
observer. If the eye is dilated to a diameter of 5 mm, what is the
minimum distance between two point...

The pupil (the opening through which light enters the lens) of a
house cat's eye is round under low light but ciliary muscles narrow
it to a thin vertical slit in very bright light. Assume that bright
light of wavelength 560 nm is entering the eye parallel to the
principal axis of the lens and that the pupil has narrowed to a
slit that is 0.500 mm wide. What are the three smallest angles on
either side to the central...

The maximum resolution of the eye depends on the diameter of the
opening of the pupil (a diffraction effect) and the size of the
light receptor cells (rods or cones) on the retina. The size of the
retinal cells (about 5.0 μm in diameter) limits the size of an
object at the near point (25 cm ) of the eye to a height of about
50 μm . (To get a reasonable estimate without having to go through
complicated calculations,...

(a) Take the diameter of the pupil of Cyclops’s eye to be 6.5
mm, and calculate the resolution angle Theta = 1.22 Lamda/ D (rad)
for light of wavelength 550 nm. For two point-objects to be
resolvable with light of this wavelength, how far apart must they
be (i) at distance 100 m? (ii) on the moon, 400,000 km away? (b)
How far apart must they be on the moon to be resolvable with a
telescope mirror of diameter 6.5...

The pupil of an eagle’s eye has a diameter of 6.0 mm. Two field
mice are separated by 0.010 m. From a distance of 201 m, the eagle
sees them as one unresolved object and dives toward them at a speed
of 18 m/s. Assume that the eagle’s eye detects light that has a
wavelength of 550 nm in vacuum. How much time passes until the
eagle sees the mice as separate objects?

The pupil of an eagle’s eye has a diameter of 6.0 mm. Two field
mice are separated by 0.010 m. From a distance of 176 m, the eagle
sees them as one unresolved object and dives toward them at a speed
of 21 m/s. Assume that the eagle’s eye detects light that has a
wavelength of 550 nm in vacuum. How much time passes until the
eagle sees the mice as separate objects?

2. Treat each of your eyes as a circular aperture of diameter
3.5 mm. Light of wavelength 625 nm is used to view two point
sources that are 10.5 cm apart. How far distance can these sources
be and still be marginally resolved by your eye? Assume that the
resolution is diffraction limited and use Rayleigh's criterion, and
the index of refraction of the fluid in the eye is 1.35.
3. A Michelson interferometer uses light with a wavelength of...

You see a light approaching you from a distance on the highway.
Is it a motorcycle (one light) or a car (two lights)? You may
assume the air is perfectly clear and still, and the headlights
emit exclusively blue light (λ = 475 nm).
Assume your pupil (the aperture of your eye) is 5 mm in
diameter. If a car with two blue headlights that are separated by
1.5 meters is approaching you, at what maximum distance could you
still...

Light can be detected when as few as 100 photons enter the eye
in an interval of 1.00 x 10^-3 s. (only about 5 of these photons
are absorbed by receptors in the retina.) What is the maximum
distance at which you could possibly see a 100 W sodium lamp
emitting light of wavelength 589 nm if your pupil is dilated to a
diameter of 6.0 mm?
