Optics is the study of light in the field of physics. It refers to the study and properties of light. Optical phenomena can be classified into three categories: ray optics, wave optics, and quantum optics. Geometrical optics, also known as ray optics, is…

Converging Lens

Converging lens, also known as a convex lens, is thinner at the upper and lower edges and thicker at the center. The edges are curved outwards. This lens can converge a beam of parallel rays of light that is coming from outside and focus it on a point on…

Plano-Convex Lens

To understand the topic well we will first break down the name of the topic, ‘Plano Convex lens’ into three separate words and look at them individually.

Lateral Magnification

In very simple terms, the same object can be viewed in enlarged versions of itself, which we call magnification. To rephrase, magnification is the ability to enlarge the image of an object without physically altering its dimensions and structure. This pr…

Textbook Question

Chapter 27, Problem 91GP

Consider a Galilean telescope, as illustrated in Figure 27-29, constructed from two lenses with focal lengths of 75.6 cm and −18.0 mm. (a) What is the distance between these lenses if an infinitely distant object is to produce an infinitely distant image? (b) What is the angular magnification when the lenses are separated by the distance calculated in part (a)?

The focal length of the lens in your eye is about 1.5 cm and the maximum size of an image that can be perceived on your retina is 5 cm (the retina is the part of your eye which acts as the screen). (a) If the object is 100 cm from your eye, where is the image produced? (b) If you want to see all of the object from this distance, what is its maximum size?

As magical as the world of Middle-Earth may be, it is still subject to the laws of nature. An individual Dwarf stands approximately 1.24 m tall and is approximately 702.3 km away from Barad-dûr, where the Eye of Sauron is perched. To what aperture must the Eye of Sauron’s rectangular pupil be opened in order to be able to resolve the head of the individual from the ground? (Ignore the width of the individual and assume an average wavelength of 580.0 nm.)

The primary optical element of the Hubble Space Telescope (HST) is 3.2 m in diameter and has a focal length of 62 m. (Treat it as a simple, single lens for this homework) The telescope is aimed at Jupiter and the collected light is focused onto a sensitive Charge Coupled Device (CCD) detector, similar to what is in a digital camera. Each pixel in the detector is a 21 μm x 21 μm square, and the full CCD is 4096 x 4096 pixels. Thus the CCD is about one square inch in size. The HST is in orbit very close to the Earth (compared to other distances in the Solar system). Size of Jupiter: 139,820 km in diameter Distance to Jupiter: 778 million km How many pixels in diameter is Jupiter's image on CCD?
