Abeam from a flashlight hits a piece of black coal and a piece of metal located 1 m away. the metal appears shiny compared to the coal. which of the following choices correctly explains how the light interacts with the coal and metal in this situation?
the metal absorbs more of the light’s energy than the coal, allowing the metal to appear shiny.
only the metal reflects some of the light. the coal does not reflect any of the light.
the metal appears shiny because it received more of the light’s energy initially, so it is able to reflect a greater amount of light than the coal.
the coal absorbs more of the light’s energy than the metal and the metal reflects more light than the coal.
