2. Draw a ray diagram for the following object and lens that shows the location, magnification and type of the image created. object -optical axis f f

Which of the following statements is not consistent with geometric optics.   a. Light rays propagate at small angles relative to the optical axis.   b. The diffraction of light is neglected.   c. Light rays propagate in straight lines.   d. Light rays propagate near the optical axis.   e. Ordinary objects always exhibit specular reflection when exposed to light.

Which of the following scenarios does NOT result in refraction? a. The light must enter the medium parallel to the normal. b. Both the incident and refracting media must be transparent. C. The light must enter the medium at an angle > 0° with respect to the normal. d. Both substances must have different indices of refraction

1. A beam of light emitted in air strikes the surface of mineral oil at the angle of 40 degreeswith respect to the normal line to the surface. Speed of light in air is 3 x 10^8 m/s in oil light travels with speed of 2.17x10^8 m/s. What is the angle of refraction? Draw the ray diagram.

An object is 8.5 cm away from a thin convex lens with focal length of f1 = 3.1 cm. 8.0 cm away from the first convex lens is a second convex lens on the same optical axis with focal length of f2 = 2.1 cm. a) Draw a principal ray diagram for the optical system including the different focal lengths, image and object distances. b) Describe the nature (real or virtual) and orientation of the final image relative to the object. c) Calculate the position of the final image after the two lenses and its magnification.

provide justification

4. Below is a diagram of an object arrow positioned such that it is bisected by the optical axis of an optical device whose focal point is as labelled. If an image of this object is viewed from the right of the optical device after the light has been affected by it, at which of the points indicated will the image of the point of the arrow be located? object a. A b. B c. C d. D e. It depends upon whether the optical device is a lens or a mirror.

Which of the following is not a problem for refracting telescopes? O A. Different wavelengths of light are focused at slightly different locations. O B. The quality of the glass lens in transparency and in the shape of both surfaces must be high. C. The secondary mirror blocks some of the light passing through the primary lens. D. The primary lens can only be supported at the edges making deformation of large lenses difficult to avoid.

4. An object is 2 meters from a thin lens with a focal length of 50 cm. Apply the thin-lens equation to calculate the image distance from the lens and magnification.

3. Show that the magnification factor for a mirror or lens M = d/d do sign convention omitted) is the lateral magnification, or the ratio of the height (lateral size) of the image to that of the object. (Draw a ray diagram)
