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.
I need parts 4-7 if possible, thank you very much.

Pre-lab The Focal length of a lens
Read the manual 0-3 thoroughly.
When an object is put in front of a thin lens, if the focal length of a lens is known, one can predict where the
image will be formed by using the thin lens equation:
Name
1 1 1
p q f
where p is the object distance, q is the image distance, and fis the focal length. fis positive for a converging
lens, and negative for a diverging lens.
Refer to the figure below to answer the questions:
A positive lens
F
9=
A negative lens
-f
1. If an object is located very far from a converging lens, i.e. poo, where would its image be formed?
9=
2. If an object is located on the first focal point of a converging lens, i.e. p=f, where is its image formed?
9. =
Is the image on the same side or opposite side of the lens as the object?
3. If an object is located on the second focal point of a diverging lens, i.e. p = f, where is its image
formed?
Is the image on the same side or opposite side of the lens as the object?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F77d2f4c8-4183-4052-877b-b5f84c5df55f%2Fa4041ed1-0c9d-494e-886f-cb421147d34a%2F3d0yywp_processed.jpeg&w=3840&q=75)

Is the image real of imaginary?
Mark the position of this image on the figure.
5. There is a negative lens to the right of the positive lens, at a distance of L= 10 cm away. What
is the distance between this negative lens and the image formed by the positive lens?
d =
6. The image formed by the positive lens is the object of the negative lens. Is the image formed by
the positive lens to the right or the left of the negative lens? In this case, is the object distance
positive or negative?

be formed by the negative lens.
q=
mark the position of this image on the figure. Is the image real or virtual?
For a diverging lens, the focal length is negative by definition. Thus in the thin lens equation, if the
object distance is positive, then the image distance will always be negative. How did we make the
diverging lens to form a real image?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F77d2f4c8-4183-4052-877b-b5f84c5df55f%2Fa4041ed1-0c9d-494e-886f-cb421147d34a%2Fjsrfhc_processed.jpeg&w=3840&q=75)
