Wave absorption occurs when a wave, like light, sound, or heat, passes through a material and the energy from the wave is taken in by the material instead of bouncing off or passing through. Different materials absorb waves in different ways. For example, dark colors like black absorb more light and heat than lighter colors, making black objects feel warmer when exposed to sunlight. Similarly, soft, porous materials, like foam, absorb sound waves and help reduce noise. On the other hand, shiny, smooth surfaces, like mirrors or metals, tend to reflect most light waves, while thick, dense materials may absorb more sound waves, reducing echoes.

Wave absorption plays an important role in many real-world situations, from how we stay cool in the sun to how buildings are designed to reduce noise. The key idea is that the amount of absorption depends on the material's properties, like color, texture, and density.

Question #1:

Response: A soft, porous foam pad
Explanation: According to the passage, soft, porous materials like foam absorb sound waves, making them effective at reducing noise.

Question #2:

Response: Black objects absorb more light and heat.
Explanation: The passage states that dark colors like black absorb more light and heat than lighter colors, which is why black objects feel warmer in sunlight.

Question #3:

Response: Sunscreen works by absorbing or reflecting the ultraviolet (UV) rays of the sun, preventing them from penetrating the skin. In terms of wave absorption, it relates to the content of the passage by functioning as a material that absorbs specific wavelengths of light (UV rays), thereby reducing the amount of energy from these waves that reaches our skin. This absorption helps to protect our skin from damage caused by solar radiation.

Question #4:

Note: Without the actual Figure 3, I cannot provide the specific labels. However, typical characteristics of waves that could be used might include:

  1. Wavelength
  2. Frequency
  3. Amplitude
  4. Speed

You would need to drag and drop these characteristics into the appropriate parts of the diagram as instructed.
