The resultant image has a height of 0.97 cm. How far from the lens is the object located? 38.9 cm 55.5 cm 88.8 cm 72.2 cm
- question is image 3.cYou have a telescope that consists of two converging lenses which are placed a distance apart which is approximately equal to the sum of their focal lengths. Focal length 1 is appriximatly 5.5cm and focal length 2 is approximatly 25cm. The lens closest to the onject should have a resonably long focal length and the eyepiece lens should have a relatively short focal length to get good magnification. a. draw a scale ray diagram for a telescope using one long and one short focal length lens. b. Estimate how much larger your distance object appears through your telescope and then calculate the angular magnification.1. draw an image in a plane mirror using equal - perpendicular lines (and describe salt) 2. draw an image in a concave mirror using 2 ray rules (and describe salt) *I will choose only 1: beyond C or at C or between C and F 3. draw an image in a convex mirror using 2 ray rules (and describe salt)
- Determine and write out the indices for the plane shown in the diagram below.Lenses with given radii. Object O stands in front of a thin lens, on the central axis. For this situation, each problem in the table (below) gives object distance p, index of refraction n of the lens, radius r, of the nearer lens surface, and radius r, of the farther lens surface. (All distances are in centimeters.) Find (a) the image distance i and (b) the lateral magnification m of the object, including signs. Also, determine whether the image is (c) real or virtual, (d) inverted from object O or noninverted, and (e) on the same side of the lens as object O or on the opposite side.

Also find the distance of end B from the HP and VP and the distance between the end projectors.
- Please give me a HAND DRAWN RAY DIAGRAM for this. Assume that the pupil of the human eye is situated 3.6 mm behind the cornea which can be approximated as a single surface of radius 7.8 mm. The aqueous fluid has a refractive index of 4/3. Give a sketch illustrating the relative positions of the pupil, cornea , the entrance pupil and the exit pupil of the optical system .Clearly indicate the Chief Ray of the above system in your diagram.A woman wears bifocal glasses with the lenses 2.0 cm in front of her eyes. The upper half of each lens has power -0.500 diopter and corrects her far vision so that she can focus clearly on distant objects when looking through that half. The lower half of each lens has power +2.00 diopters and corrects her near vision when she looks through that half. (a) What are the far point and near point of her eyes? (b) While the woman is repairing a leaky pipe under her kitchen sink, she looks at close objects through the upper half of her bifocal lenses. What is the closest object that she can see clearly?Light from a source A at (−1, 1) is reflected by a plane mirror placed along the x-axisto a receiver B at (2, 2).(a) For a given point (x, 0) between A and B on the x-axis, find the distance betweenA and (x, 0) and the distance between B and (x, 0). Your answers should dependon x.(b) Denote by D(x) the sum of the two distances you found in the part (a), thoughtof as a function of x. Find D0(x).(c) Find the absolute minimum of D(x) on the x-interval [−1, 2].(d) The light from source A reflected by the mirror to receiver B will travel theshortest distance possible (more precisely, light will obey Fermat’s principle). Atwhat point P on the x-axis between A and B does the light hit the mirror?
