identify at least one example each of absorption, transmission, reflection, and refraction of waves in this…

Brief Explanations:

• Absorption: Water molecules absorb some light energy (e.g., certain wavelengths), causing the water to heat slightly or the light intensity to reduce with depth.
• Transmission: Light waves pass through the water, allowing us to see the underwater scene (like the swimmer and the water below the surface) as light transmits through the water medium.
• Reflection: The water surface reflects light, creating a mirror - like image of the underwater waves or the sky (if visible from the surface perspective), similar to how a mirror reflects light.
• Refraction: When light moves from air to water (or vice - versa), its direction changes. For example, the apparent position of the swimmer's body or the underwater objects may seem shifted due to refraction at the water - air interface.

For drawing models:

• Absorption: Draw a wave approaching a water - like medium, with shorter waves (or reduced amplitude) after entering, indicating energy absorption.
• Transmission: Draw a wave passing through a rectangular (representing water) with the wave continuing on the other side, showing the wave's path through the medium.
• Reflection: Draw a wave hitting a surface (water surface) and bouncing back at an equal angle (law of reflection), with an incident wave and a reflected wave.
• Refraction: Draw a wave approaching a boundary (air - water), with the wave bending as it enters the water (change in speed and direction), showing the incident, refracted, and normal lines.

Answer:

• Absorption: Light absorption by water molecules.
• Transmission: Light transmitting through water to show underwater scene.
• Reflection: Light reflection at water surface.
• Refraction: Light bending at air - water interface. (And the corresponding model drawings as described above.)
