When a ray of light is incident on clear glass and silver metal then most of the light is transmitted through the clear glass and none of the light passes through the silver metal.
This is so because the clear glass is a transparent substance and silver metal is a opaque and no light can pass through it.
The light gets transmitted through the clear glass and the light gets reflected back which strikes the metal surface.
Erosion is the breakdown of anything. Like for example rock erosion is when the water keeps hitting the rock over and over until then the rock sarts to breakdown.
