This document explores the use of Boomwhackers, a musical instrument, as a teaching tool for physics concepts related to sound waves. The author suggests using Boomwhackers to play Beethoven's "Ode to Joy" and then delving into the speed of sound. The focus is on the relationship between sound frequency and tube length, as well as the concepts of pitch and octaves. The document provides a step-by-step procedure for conducting experiments with Boomwhackers to help students grasp these concepts. It concludes that students can learn about fundamental frequency, pitch, octave, and the speed of sound through this activity, even without prior knowledge of physics. [Extracted from the article]

Students may have some confusion understanding certain physical concepts and principles because of their abstract nature. Using analogies is one of the useful methods to help them more easily grasp abstract concepts to promote conceptual understanding. Bilaloğlu classified analogies in four groups: (a) simple analogies, (b) storified analogies, (c) gamified analogies, and (d) analogies made with painting. In storified analogies, it is attempted to teach an event, phenomenon, concept, or principle by using an oral or written story. [ABSTRACT FROM AUTHOR]

This article deals with the properties of polarized light from a laptop computer screens. Liquid crystal diode (LCD) screens emit plane polarized light. Typically, the LCD screens are designed so that the plane of the polarized light from it is at 45° from the edges of the screen so that a person wearing polarizing glasses can still see the screen, though not as bright. The rotation of plane of polarization by reflection is discussed.

This article describes a method for determining linear coefficient of thermal expansion using reading available materials. The design of the apparatus for this method is noted. The experimental set-up is discussed. The device used to obtain a diffraction pattern for the single slit is mentioned. Some helpful pointers for physics teachers are offered.
