Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer .

In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology , sound is the reception of such waves and their perception by the brain . [ 1 ]
Punjab Curriculum and Textbook Board was established in 1962 as West Pakistan Textbook Board. [3] Its functions are curriculum development, implementation of educational policies of the Government, publication of textbooks and production of supplementary reading material relating to textbooks. [4]
Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area, also called the sound power density and the sound energy flux density. [2] The SI unit of intensity, which includes sound intensity, is the watt per square meter (W/m 2).
In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space. The peak amplitude of the wave oscillations at any point in space is constant with respect to time, and the oscillations at different points throughout the wave are in phase .
The Centre for High Energy Physics (CHEP) is a federally funded national research laboratory managed by the University of Punjab. [1]The CHEP is dedicated towards the scientific advancement and understanding of high energy physics (or particle physics) — a branch of fundamental physics that is concerned with unraveling the ultimate constituents of matter and with elucidating the forces ...
A primary school book published under Sarva Shiksha Abhiyan Punjab. Sarva Shiksha Abhiyan was started in 2000s by the government of India to provide free and compulsory education to the children from 6 to 14 years of age. [9] In August 2024, Punjab government announced that it is planning to start a new project called "Schools of happiness".
