Physics 9

A physics book used in Swedish primary schools that covers areas such as nuclear physics, optics, and cosmology. The textbook is richly illustrated with educational images, video clips, and study assignments. The content is also very up-to-date with the latest developments in nuclear physics. In cosmology, it also covers exoplanets and methods to discover them. The chapter on optics, in addition to light's refraction and reflection, also addresses the speed and duality of light, reinforced with filmed experiments and conclusions that can be drawn from the experimental results.
