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…

Students have asked these similar questions

The contacts worn by a farsighted person allow her to see objects clearly that are as close as 25.0 cm, even though her uncorrected near point is 75.0 cm from her eyes. When she is looking at a poster, the contacts form an image of the poster at a distance of 155 cm from her eyes. (a) How far away is the poster actually located? (b) If the poster is 0.380 m tall, how tall is the image formed by the contacts? (a) Number i Units (b) Number i Units

The person cannot see the objects beyond 15.0 cm distance from the eye. This means, the far point of the person’s eye is 15.0 cm.

(a)A goldfish is swimming at 5.40 cm/s toward the front wall of a rectangular aquarium. What is the apparent speed (in cm/s) of the fish measured by an observer looking in from outside the front wall of the tank?_____cm/s (b)What If? The fish is now gently transferred to a spherical bowl with a radius of curvature R = 30.0 cm. If it again swims at 5.40 cm/s along a radial line toward the outside of the bowl, what is the apparent speed (in cm/s) of the fish measured by an observer looking in from outside the front wall of the tank, when the fish is 3.80 cm from the wall?_____cm/s
