0: Images Еyes Acuvity Our eyes use a biconvex lens behind our pupil to focus incoming light into images on the retina at the back of our eyes. Human eyes have a diameter of approximately 2.5 cm on average. Imagine a 1.8 m tall person stands 2 m away from you. 1.8 m 2.0 m 0.025m *Image not drawn to scale 18 Draw a ray diagram showing how the light coming from this person passes through the lens in your eye and produces an image on your retina.

Activity: Crossword Puzzle Directions: Answer the crossword puzzle using the given set of definitions. Across: 2. The angle of incidence is equal to angle of reflection. 4. Polished reflecting surface that produces an image. 5. The angle between the incident ray and the normal. Down: 1. The ray that leaves the reflecting surface. 3. The ray that approaches a reflecting surface.

1. How might you determine the focal length more accurately? 2. How does the size of the image of object compare to the object itself?

Explain completely and easily about the ray diagrams for correcting myopia,hyperopia and astigmatism and draw them with easy complete explanations, then write about the importance of lenses and mirrors

Physics104 lab: Spherical Mirrors(concave, convex) ***VERY IMPORTANT NOTE Please answer this question in a very sensible manner by explaining your idea in a figurative and descriptive way. Plz, don't copy the answer from Chegg or any other as those answer doesn’t make any sense.   Q) Describe the behaviour of the reflected beam when it is aimed near the edges of the mirror. What do you think causes this?

Nearsightedness and Farsightedness 10 of 10 Constants A person with normal vision can focus on objects as close as a few centimeters from the eye up to objects infinitely far away. There exist, however, certain conditions under which the range of vision is not so extended. For example, a nearsighted person cannot focus on objects farther than a certain point (the far point), while a farsighted person cannot focus on objects closer than a certain point (the near point). Note that even though the presence of a near point is common to everyone, a farsighted person has a near point that is much farther from the eye than the near point of a person with normal vision. Both nearsightedness and farsightedness can be corrected with the use of glasses or contact lenses. In this case, the eye converges the light coming from the image formed by the corrective lens rather than from the object itself. Part B If a nearsighted person has a far point de that is 3.50 m from the eye, what is the focal…

Post-Lab Question In a refracting optical telescope, a real image of a distant object is produced in the space between the lenses. A second lens produces a magnified virtual image. Below is a ray diagram of the two lenses, the real image, and the virtual image. Object Objective lens Virtual image Eyepiece Real image Figure 2: Ray Diagram of a Telescope 1. Research and sketch a ray diagram of the Galilean telescope.

Geometrical optics. Optical systems 1. Thin lens equation Consider a lens having an index of refraction n and two spherical surfaces with radii of curvature R1 and R2, as in Figure. An object is placed at point O at a distance p in front of surface. The focal length f of a thin lens is the image distance that corresponds to an infinite object distance R1 R C2 p'a f – lens focal length (m); p – distance from the object to the lens or object distance (m); q – distance from the image to the lens or image distance (m). Sign Conventions for Thin Lenses p is positive if object is in front of lens (real object). p is negative if object is in back of lens (virtual object). q is positive if image is in back of lens (real image). q is negative if image is in front of lens (virtual image). f is positive if the lens is converging. fis negative if the lens is diverging. OC(ICI (a) 2. Magnification of Images The lateral magnification of the lens is defined as the ratio of the image height H to the…

Activity: A glass of water sits on top of a table. You are looking down from the side of the glass to see a coin at the bottom of the glass with water. How many times the ray of light bends coming from your eyes going to the coin inside the glass. Where will the light travels fastest and the slowest and explain why.
