2. A student plays the cymbals in a band. When the cymbals are hit together, a loud sound is produced. The force of the cymbals hitting each other produces sounds because _____. • metal conducts heat • energy is absorbed • metal is magnetic • air vibrates Next Question

3. 2. The famous scientist Isaac Newton conducted an experiment. He used a strong beam of light coming in through a small hole to pass through a prism. He caught the light falling on the opposite wall. To his surprise he found that the white light that came through was split into colored bands on the wall. How can this be explained? • The colored bands are formed by the wall. • These bands appear whenever light falls on a wall. • The light is made of waves of different wavelengths that are split apart by a prism. • The prism absorbs all the white light and allows all colored light through.
