Abstract

The aim of this research is to introduce students to the basic concepts of sound and light during science learning. This abstract discusses the properties of sound, such as its source, propagation, and how the human ear receives sound. Apart from that, this abstract also discusses light as an energy source that allows us to see objects around us, including how the eye propagates and receives light. Once students understand these concepts, it is hoped that they will be able to understand between sound and light.Sound waves can modulate the amplitude and phase of light, bending it, focusing it, or shifting its frequency. Light can create visible acoustic images or provide detailed information about thermal vibrations in solids and liquids. Diffraction of light waves by sound waves takes several different forms, depending on the two wavelengths and the dimensions of the interaction region.

Diffraction of light waves by sound waves has several different forms, depending on the two wavelengths and the dimensions of the interaction area. Sound is a wave produced by a vibrating object. Meanwhile, light is energy that has electromagnetic waves and can propagate in a vacuum. Sound can travel through solids, liquids and gases.

Abstract

Schools and communities are two inseparable things. The community is expected to support and participate in the development of the educational process in schools. The research aims to describe the pattern of relationships between schools and society. In this case, the one who is in charge of being a bridge between the school and the community is a Public Relations. One of the roles of a Public Relations is to foster good relations with the community. Public relations officers must have a good attitude and be able to solve problems wisely. The importance of school and community relationships can achieve school goals. One of the goals of a public relations officer is to create a good image for his school and be able to influence the community to work together to realize a better quality education. In addition, a public relations officer has a well-organized planning function so that the goals and perfect implementation can be achieved. In the implementation of public relations, of course, there are challenges, therefore solutions and strategies are needed by improving the relationship between student guardians and the school.
