- Mirrors reflect light due to the law of reflection, where the angle of incidence equals the angle of reflection.
- There are two main types of mirrors: plane mirrors with flat surfaces, and curved mirrors that can be either convex with bulging outward surfaces or concave with bulging inward surfaces.
- Ray diagrams use rays of light to determine the location, orientation, and size of images formed by mirrors and lenses.

Most of the times this study confused me...so, i just put some important points in one place to easily keep them in mind..hope it will help other students as well..and inform me, if a reader find anything new to improve it further.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
Macroeconomics- Movie Location
This will be used as part of your Personal Professional Portfolio once graded.
Objective:
Prepare a presentation or a paper using research, basic comparative analysis, data organization and application of economic information. You will make an informed assessment of an economic climate outside of the United States to accomplish an entertainment industry objective.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
18. Curved mirror
A curved mirror is a mirror with a curved reflecting
surface. The surface may be either:
-CONVEX (bulging outward)
-CONCAVE (bulging inward)
Most curved mirrors have surfaces that are shaped like
part of a sphere, but other shapes are sometimes used
in optical devices.
19. CONCAVE MIRROR
• Concave mirrors are used:
- in reflecting telescopes.
-provide a magnified image of
the face for applying make-up or
shaving. In illumination applications,
in torches, headlamps and spotlights,
-used to form optical cavities,
which are important in laser
construction
-landing aid system of
modern aircraft carriers also uses a
concave mirror.
32. Ray diagram
- Is used for determining the
characteristics of an image formed in
mirror or through lens…
33. RAY DIAGRAM
•Is a tool used tool used to
determine the location,
orientation, an size of an
image formed in a mirror or
through a lens.
34. TERM SYMBOL DESCRIPTION
Vertex V The center of the
mirror
Center of
curvature
C The center of the
spherical
Radius of
curvature
R The distance from the
center
Spherical
diameter
D The diameter of the
spherical mirror
35. TERM SYMBOL DESCRIPTION
Focal Point F This is a point where all rays
converge or seem to converge. It
is also called focus.
Focal length f The distance between the focal
point and the vertex. Can be
obtained by dividing the radius of
curvature by 2.
Principal axis A line passing through the
center of curvature and the
vertex of the mirror
Normal A line perpendicular to the
surface of a mirror
