Waves can transfer energy and travel through different mediums like solids, liquids, and gases. A wave has a wavelength, which is the distance between peaks, a frequency, which is the number of waves in a given period of time, and a speed. There are two categories of waves: transverse waves, where the medium moves perpendicular to the direction of travel, and longitudinal waves, like sound waves, where the medium compresses and expands along the direction of travel. Waves can reflect, refract, and diffract as they interact with objects and change mediums.
Learn how sound, vibrations, and waves all relate to each other by using simple physics equations. Included GIFs to understand the physical representation of each concept.

Sound waves are produced by the vibration of material objects. A disturbance in the form of a longitudinal wave travels away from the vibrating source. High-pitched sounds are produced by sources vibrating at high frequency, while low-pitched sounds are produced by low-frequency sources Sound waves consist of traveling pulses of high-pressure zones, or compression, alternating with pulses of low-pressures zones, or rarefaction. Sound can travel through gases, liquids, and solid, but not through a vacuum.

This presentation is about the introduction and characteristics of sound. Including the subtopic on the Pressure and Intensity of sound waves, Pitch, Resonance effect in sound systems, and Helmholtz resonator, Reflection and diffraction of sound waves. In this presentation you will know and understand how sound is created and why sound needs a medium in order to be recognized by someone (animals or human). The uses of different sound wave frequency in different field of study.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
