Question

when an electromagnetic wave reaches a material boundary, different results are possible.
match each result with its description by dragging the tiles.
result\tdescription
absorption\tthe wave bounces back after reaching the boundary
transmission\tthe wave crosses the boundary and travels through the material
reflection\tthe wave’s energy is taken in by the material and converted to another form

Explanation:

• For "absorption", the description is "the wave’s energy is taken in by the material and converted to another form" because absorption involves a material taking in wave energy and transforming it (e.g., light energy to heat).
• For "transmission", the description is "the wave crosses the boundary and travels through the material" as transmission means the wave passes through the material after crossing the boundary.
• For "reflection", the description is "the wave bounces back after reaching the boundary" since reflection is the bouncing back of a wave from a boundary.

Answer:

• absorption: the wave’s energy is taken in by the material and converted to another form
• transmission: the wave crosses the boundary and travels through the material
• reflection: the wave bounces back after reaching the boundary
