To correct the vision of a hyperopic eye, a corrective lens should enable the wearer to focus or objects that are as close as the ideal near point. One way to think of this is that the corrective lens should take an object located at the ideal near point and create an image of it at the wearer's near point. (Remember that the wearer's eye is a short distance behind the corrective lens.)

Concept explainers

Radiation

Radiation can be described as the energy in the form of a particular matter or electromagnetic waves traveling in the air and can be in the form of light, sound, and heat. Radiation can be detected through special instruments like X-rays. The radiation from a cooler object is less intense as compared to the radiation from hot objects.

Question

To correct the vision of a hyperopic eye, a corrective lens should enable the wearer to focus on
objects that are as close as the ideal near point. One way to think of this is that the corrective
lens should take an object located at the ideal near point and create an image of it at the
wearer's near point. (Remember that the wearer's eye is a short distance behind the corrective
lens.) Draw a ray diagram showing this situation and find the necessary focal length of the lens
in terms of the wearer's near point, the ideal near point, and the distance between the
corrective lens and the eye.

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.

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…

Two point sources of coherent light with a wavelength of 700 nm are near each other. The light from these sources is interfering in space around them. If you determine there is destructive interference between the two sources at a point 70.35 μm away from the second source, how far away from this point might the first source be? (Note that the image shown is not drawn to scale.) Source 1 74.20 μm o 77.175 um - 80.85 um ○ 80.85 μm 80.85 μm ? Source 2 70.35 μm destructive interference here
