Concept explainers

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 75PCE

Roughing It with Science A professor shipwrecked on Hooligan’s Island decides to build a telescope from his eyeglasses and some coconut shells. Fortunately, the professor’s eyes require different prescriptions, with the left lens having a power of +5.0 diopters and the right lens having a power of +2.0 diopters (a) Which lens should he use as the objective? (b) What is the angular magnification of the professor’s telescope?

Students have asked these similar questions

The near point of a person's eye is 51.2 cm. (Neglect the distance from the lens to the eye.) (a) To see objects clearly at a distance of 27.0 cm, what should be the focal length of the appropriate corrective lens? cm (b) To see objects clearly at a distance of 27.0 cm, what should be the power of the appropriate corrective lens? diopters

1) Calculate the magnification of the 36-in refractor at Lick Observatory on Mount Hamilton near San Jose, California. The focal lenght of the objective lens is 17.37m, and the focal lenght of the eyepiece is 22 mm. (Express your answer to three significant figures.) 2) What is the significance of the negative sign in the magnification equation? a) The image is inverted when viewed in the eyepiece. b) The image is upright when viewed in the eyepiece.

People who do very detailed work close up, such as jewelers, often can see objects clearly at a much closer distance than the normal 25.0 cm. What is the power of the eyes of a woman who can see an object clearly at a distance of only 8.25 cm? Assume a distance from the eye lens to the retina of 2.00 cm. power: diopters What is the size of the image of a 2.00 mm object, such as lettering inside a ring, held at this distance? Enter your answer as a positive number if the image is upright and negative if it is inverted. image size at 8.25 cm: mm What would the size of the image be if the object were held at the normal 25.0 cm? image size at 25.0 cm: mm
