A patient cannot clearly see any object that lies closer than 31.0 cm to his left eye. However, the patient wishes to see objects as close as 20.0 cm with that eye. The patient requests eyeglasses to address the problem. (a) Is the patient nearsighted or farsighted? O nearsighted O farsighted (b) If the eyeglass lens lies 2.06 cm in front of the patient's eye, what is the minimum distance p (in cm) separating the lens from an object he wants to see? (Give your answer to at least three significant digits.) cm (c) The patient is unable to focus clearly on anything closer than 31.0 cm to his eye (this being the patient's near point). The image formed by the eyeglass lens must therefore be 31.0 cm from the eye. How far, then, (in cm) would the image lie from the lens? (Give your answer to at least three significant digits.) cm (d) The image lies on the same side of the lens as the original object. Is the image real or virtual, and is its position a positive or negative? (Select all that apply. Note that your answer to the previous part is the absolute value of the image position, or Igl.) Oreal image virtual image distance is positive O distance is negative (e) What is the lens focal length f (in cm)? cm (f) Compute the power (in diopters) that corresponds to this focal length. diopters (g) Suppose now that the patient desires contact lenses instead of eyeglasses. What values of p, q, f, and power P would describe the correct contact lens for the eye under discussion? (Enter p and q to at least three significant digits. Enter p, q, and fin cm. Enter P in diopters.) p = 9 = f = P = cm cm cm diopters
Ray Optics
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 an optics model that explains light propagation using rays. In an optical device, a ray is a direction along which light energy is transmitted from one point to another. Geometric optics assumes that waves (rays) move in straight lines before they reach a surface. When a ray collides with a surface, it can bounce back (reflect) or bend (refract), but it continues in a straight line. The laws of reflection and refraction are the fundamental laws of geometrical optics. Light is an electromagnetic wave with a wavelength that falls within the visible spectrum.
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 the other side of the lens.
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 process is mainly done to get an even more detailed view of the object by scaling up the image. A lot of daily life examples for this can be the use of magnifying glasses, projectors, and microscopes in laboratories. This plays a vital role in the fields of research and development and to some extent even our daily lives; our daily activity of magnifying images and texts on our mobile screen for a better look is nothing other than magnification.
