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 26, Problem 16CQ

People who do very detailed work close up, such as jewellers, often can see objects clearly at much closer distance than the normal 25 cm. (a) What is the power in D of the eyes of a woman who can see an object clearly at a distance of only 7.30 cm? (Assume the lens-to-retina distance is 2.00 cm.) ____D (b) What is the size in mm of an image of a 6.00 mm object, such as lettering inside a ring, held at this distance? (Include the sign of the value in your answer.) ______mm (c) What would the size of the image be in mm if the object were held at the normal 25.0 cm distance? (Include the sign of the value in your answer.) _____mm
