A beam of light incident on the metal surface is reflected. Reflection involves two rays - an incoming or incident ray and an outgoing or reflected ray. In Figure 1 we use a single line to illustrate a light ray reflected from the surface. lawn mower air filter housing

"WebJan 4, 2024 · Metal. Metals tend to have a flat shape and a polished surface, which usually makes them highly reflective. Aluminum, copper, and steel can all amplify and enhance sound waves. In fact, steel has a sound absorption coefficient of only 0.03, which means that it can only absorb about 3% of all sound waves that hit it. " - Does metal reflect light
