Question

drag the name of the type of wave to the correct picture

Explanation:

• Reflection: When a wave bounces off a surface. In the second image, the wave seems to bounce off the large block.
• Absorption: When a wave's energy is taken in by a material. There is no clear indication of absorption in the given images.
• Refraction: When a wave bends as it passes from one medium to another. In the third image, the wave bends as it passes through the lens - like object.
• Diffraction: When a wave spreads out as it passes through an opening or around an obstacle. In the fourth image, the wave spreads out after passing through the slit.

Answer:

1. Reflection
2. Absorption (There is no correct match in the given images for absorption as per the standard wave - behavior definitions, but if we assume the second image as absorption wrongly, this is the label)
3. Refraction
4. Diffraction
