You 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.

A microscope is composed of an objective convex lens (L1) with a focal length of 5 cm and a convex eyepiece (L2) with a focal length of 11 cm, which is located 40 cm behind L1. Six centimetres in front of Draw ray diagram and explain picture is an ant. Calculate the interval between L1 and the image's magnification.
These images show one of the large `VLT’ telescopes at the European Southern Observatory’s facility at Cerro Paranal, Chile. The place where the laser beam comes out (seen in the inset photo) is just out of sight off of the top edge of the large photo. Also note that if you look down the telescope tube (in the main photo), you can see the tube’s front-end structure. Why is there a laser beam shooting out of the front of this telescope (in the inset picture)? Group of answer choices The beam creates an `artificial star’, which is used by an adaptive-optics system to measure (and counteract) the blurring effect of Earth’s atmosphere. The astronomers are bouncing light off of objects near the center of the Milky Way galaxy, to measure their distances from Earth. The astronomers are taking pictures of the surface of a planet (most likely Mars), and the laser allows them to light up the planet’s surface with a very specific color of light. The astronomers are engaged in the opening…
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?
In a biprism experiment, the slit is illuminated by the light of wavelength 5890A.the distance between the slit and eye piece is 0.8m.the two virtual images of the slit are formed 0.2cm apart. Calculate the change in fringe width if the eye piece is displaced 10cm away from the slit.

The sun is the only star whose size we can easily measure directly; astronomers therefore estimate the sizes of other stars using Stefan's law. The spectrum of the star Betelgeuse, plotted as a function of energy, peaks at a photon energy of 0.8 eV, while Betelgeuse is approximately 10,000 times as luminous as the sun. How does the radius of Betelgeuse compare to the sun's radius? Why is Betelgeuse called a "red supergiant"?
