Reflection of Waves

Science > Physics > Wave Motion > Reflection of Waves In this article, we shall study the reflection of waves at the boundary of the denser medium and rarer medium. Wave in a medium may be defined as the disturbance moving through the medium without change of form. e.g. ripple in water formed due to […]
