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.
Hello,
I need help answering Q2 and Q3.
Thank you!
![Q2. Once you have drawn in the three principal rays, insert this line with an arrowhead to

If each small square of the "graph paper" of Figure 3 you just used is 1 cm in length,
carefully measure the following:
f=
7.5 CM
do =
11.5CM
h. =
3CM
Figure 3: Ray tracing diagram for the converging lens part of the activity, with do >f.
The object is located to the left of the lens.
di =
7.5CM
h; =
2CM
For a thin lens, allow all bending (refracting) to take place along the vertical line drawn
along the center of the lens.
Using thin lens Equations 1 and 2, calculate di and M. Show your work and clearly
highlight your answers: either use the equation editor or take a photo of your work
and insert it.
Directly on Figure 3, insert the three principal rays (discussed below) for a converging
lens, with d. > f. You may copy/paste this line segment (-
many times as necessary to create the three principal rays. To reposition the line segment,
click and drag it or click and use the arrow keys. To change its beginning or end position
(or angle), click one end of the line and drag in the desired direction. Choose a different
color for each ray and label each ray as described in the boxed text below. [Hint: Also
refer to Figure 2(a) to see how each ray is drawn.]

Though there are many light rays that emanate from an object in all directions, in order to
locate the image formed by a lens, we need only consider the three principal rays that
propagate through the lens.
Q3. Do your calculated and measured values for di and Magree? Explain any
discrepancies and correct if necessary.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F43da8127-b8b5-4d0a-8317-0b1da88f2197%2F6368e971-e16c-472c-8a5f-af242862ae13%2Fd8blka_processed.png&w=3840&q=75)
