When an object is placed at a distance d, from a lens of focal length f, and d, is greater than f, the rays hitting the lens will form a real image on the other side, at a distance d; from the lens. The object distance do, image distance d;, and focal length f are related by the "Thin Lens Equation": 1 1 1 f do' di The height of the image h; is usually different than the height of the original object ho. The factor by which the image is bigger than the object is called the Magnification M of the image. The magnification depends on the distances d, and d; if the image is farther from the lens than the object, it will be bigger than the object. hị M di ho do If the magnification is positive, the image is "right side up"; if it is negative, the image is upside down or "inverted." In this exercise, you will use the above equations to see what happens to the image as you move an object closer and closer to the lens. We are looking for patterns, to see how the variables change in relation to each other. Directions: Here are some practice problems to make you familiar with these concepts. Please review the following. An object is placed at four different distances from a convex lens with f = 20.0 cm: a) do = 60.0 cm b) do = 50.0 cm c) do = 40.0 cm d) do = 30.0 cm %3D %3D
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.
