Physics Chapter12WhatIsLight99 12.1 Introduction Everything we see, we see because of light. Our eyes pick up light that interacts with and bounces off objects. We see colors, shapes, sizes, and tex

100ExploringtheBuildingBlocksofScienceBook4 But when the light reaches the chemicals on the photographic film, it behaves like a particle. As each particle of light hits a point on the photographic fi

Physics Chapter12WhatIsLight101 12.2 Photons Light is made of photons. A photon is a packet of energy that has a particular frequency and travels through space like a wave. Although physicists curre

102ExploringtheBuildingBlocksofScienceBook4 The only difference between different forms of electromagnetic radiation is the frequency or wavelength of their waves. Radio waves have low frequencies and

Physics Chapter12WhatIsLight103 The different wavelengths are the different colors we see. Red light has the longest wavelength in the visible spectrum, and violet light has the shortest wavelength.

104ExploringtheBuildingBlocksofScienceBook4 The colors in fireworks are created when this heat energy is absorbed by the atoms of the metallic chemicals in the firework. When metal atoms are quickly h
