A charged-couple device (CCD) detector ismounted at the focus of an f/7 reflecting telescope with a D= 50 cm mirror. The CCD chip contains 1024×1024 pixels, with each square pixel being 10μm on a side.
What is the area (in square arcminutes) of the sky that is imaged on the entire chip?
A small telescope has a concave mirror with a 2.6 m radius of curvature for its objective. Its eyepiece is a 3.4 cm focal length lens.
Part (b) What angle (in degrees) is subtended by a 25,000 km diameter sunspot? Assume the sun is 1.50 × 108 km away.
Part (c) What is the image angular size (in degrees) in this telescope?
You are given a plano-convex lens with radius of curvature 69.7 mm on the curved side. The lens is made of BK7 which has refractive indices of 1.5243 at 461 nm, and 1.5134 at 689 nm. If you shone collimated beam of 461 nm and 689 nm light through the same lens, what would be the (positive) difference in their focal lengths in mm? [Aside: these wavelengths are used in highly accurate cold strontium atomic clock experiments]

- You have a telescope with a 125 cm focal length objective. Recall that simple two-element telescopes invert the images of the objects viewed through them. What is the angular magnification, M, of this telescope when equipped with a 2.25-cm focal-length eyepiece? M =arrow_forwardThe primary mirror on a telescope is able to resolve objects that are theta o apart.

- People are often bothered when they discover that reflecting telescopes have a second mirror in the middle to bring the light out to an accessible focus where big instruments can be mounted. “Don’t you lose light?” people ask. Well, yes, you do, but there is no better alternative. You can estimate how much light is lost by such an arrangement. The primary mirror (the one at the bottom in Figure 6.6) of the Gemini North telescope is 8 m in diameter. The secondary mirror at the top is about 1 m in diameter. Use the formula for the area of a circle to estimate what fraction of the light is blocked by the secondary mirror. Figure 6.6 Focus Arrangements for Reflecting Telescopes. Reflecting telescopes have different options for where the light is brought to a focus. With prime focus, light is detected where it comes to a focus after reflecting from the primary mirror. With Newtonian focus, light is reflected by a small secondary mirror off to one side, where it can be detected (see also Figure 6.5). Most large professional telescopes have a Cassegrain focus in which light is reflected by the secondary mirror down through a hole in the primary mirror to an observing station below the telescope.arrow_forwardThe NTT telescope has a 3.58 m primary mirror and a focal ratio of f/2.2. a.

What is the index refraction of the glass? 2. In order to magnify an image, you are swapping your standard 40mm focal length lens with a telephoto lens that has a much bigger focal length of 860 mm.

- ) A converging lens of focal length 6.25cm is used as a magnifying glass. If the near point of the observer is 25 cm from the eye and the lens is held close to the eye, calculate i) the distance of the object from the lenses ii) magnification and iii) magnification when the final image is formed at infinity. iv) draw diagrams to show magnification in both the cases.arrow_forwardThe light beam in the figure below strikes surface 2 at the critical angle, ?c = 42°. Determine the angle of incidence, ?1. ° A prism in the shape of an equilateral triangle is shown. The triangle is upside down such that the base of the triangle is at the top of the figure and the apex is at the bottom. A light ray comes in from the top left, moves down and to the right and is incident on the center of the base of the triangle. This surface is labeled Surface 1. The incident ray makes an angle of ?1 with the vertical. Within the prism, the ray continues to move down and to the right but at a slope which is steeper than the initial ray. It is incident on the right side of the prism, labeled Surface 2, about two-thirds of the way down and makes an angle of 42.0° with the normal. Some of the ray is reflected, making an angle of 42.0° with the normal, and moves down and to the left. The rest of the ray moves down and to the left but at a steeper slope than the previous ray, and moves…arrow_forwardIn X-ray imaging, to achieve a well-defined small area of X-ray beam, the anode of the X-ray tube is usually bevelled.
