An object of height 5-cm is placed 250-cm from a converging lens of focal length 75 cm. (a) Draw the ray diagram about where the image will form. Using thin lens equation, find image distance and height of the image. (b)Draw ray diagram if the object is placed 50 cm away from the lens plane? Using thin lens equation, find image distance and height of the image.

An object is placed at the center of curvature of a double concave lens, both ofwhose radii of curvature have the same magnitude. Find the image distance in termsof the radius of curvature r and the index of refraction n of the glass. Describe thenature of the image. Verify your result with a ray diagram.

A magnifying glass is taken out on a sunny day and it concentrates sunlight to a small spot 8.0x 10-2  from the lens center.  Calculate  a) the focal length of the lens  b) the power of lens

The radius of curvature of a spherical convex miror is 20 cm. 1) Describe the image formed when a 10-cm tall object is positioned 50 cm from the mirror. Calculate the image distance dI. Follow the sign convention. (Express yor answer to two significant figures). 2) Calculate the image height and describe the orientation. (Express yor answer to two significant figures). 3) Describe the image formed when a 10-cm tall object is positioned 100 cm from the mirror. Calculate the image distance dI. Follow the sign convention. (Express yor answer to two significant figures). 4) Is the image real or virtual? 5) Calculate the image height and describe the orientation. (Express yor answer to two significant figures).

If an object is place 15 cm away from a converging lens focal length Sem, the image formed will he: 41. On the same side of the lens as the object. Real and inverted. Exactly half as tall as the object 2. 3.

A 2.65 cm diameter coin placed a distance of 32 cm from a diverging lens that has a focal length of -14.0. What is the image distance and the diameter of the image?

A glass sphere (n = 1.50) with a radius of 16.0 cm has a tiny air bubble 4.30 cm above its center. The sphere is viewed looking down along the extended radius containing the bubble. What is the apparent depth of the bubble below the surface of the sphere? 7.936 Apply the equation relating the object distance, image distance, and radius of curvature for a spherical refracting surface. cm Need Help?

Determine the distance of an object that forms an image at 39cm away from the converging lens that had a focal length of 10cm. Round to the nearest whole number.

(Dove Prism) A new type of prism inverts an image that comes in through one end (see Figure 1). The prism will be shaped like a trapezoid with a square cross-section and sides cut at a 45° angle, and that the prism will be made of a plastic called BK7 that has an index of refraction of 1.517. Decide on the dimensions of the prism in order to maximize the size of the image that can be inverted (see incoming/outgoing rays in the side view in Figure 2). How long (length B in Figure 1) should the prism be in terms of its height (length A in Figure 1)? What happens to an image that enters the prism on one side of its long face (see figure 3)? Make a drawing tracing the path of rays 4, 5, and 6 in figure 3 to find out. Figure 1 Figure 2 1 3 2 45° 3 1 Figure 2 Figure 3 45° Figure 3 4 5 6

A force of: F = (23i+16j-51K)N is applied to a particle of mass 15-kg. The particle has a speed of 10 m/s when the force is applied and is at coordinates: (6,-10,8)m. Under the application of this force. the particle moves to a new position: (25,-21,-10)m.Determine: a) The work done by the force on the particle over this interval b) The speed of the particle at the end of this interval
