Question 2 The relation between the position of the image and object for a thin lens is given by the thin lens equation: 1 1 do +a, =7 where f is the focal length of the lens. Using the fact that 1 divided by a very large number is nearly 0, show that the thin lens equation predicts that an object located at the focal point gives an image that is infinitely far away, that is, when d; is very large, do = f.

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, 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…

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.

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…
