The Correct Answer and Explanation is:
Here are the correct matches for each wave interaction:
- Reflection: The bouncing of a wave after it hits an object.
- Diffraction: The bending and scattering of a wave as it hits an object or opening.
- Refraction: The bending of a wave as it passes through media.
- Absorption: The taking in of a wave by an object as the wave hits it.
- Transmission: The passing of a wave through an object.
Explanation:
- Reflection:
Reflection occurs when a wave strikes an object or surface and bounces back without passing through. This can be seen with light waves, sound waves, and water waves. For example, when light strikes a mirror, it bounces back, allowing us to see a reflection of objects. In physics, the angle at which the wave hits the surface (incident angle) equals the angle at which it reflects (reflected angle), known as the law of reflection. - Diffraction:
Diffraction refers to the bending and spreading of waves around obstacles or through openings. This phenomenon is most evident with sound waves, light waves, and water waves, especially when the size of the obstacle or opening is similar to the wavelength of the wave. For instance, when sound waves pass through a doorway, they spread out, allowing the sound to be heard even when not directly in front of the door. - Refraction:
Refraction occurs when a wave passes from one medium into another and changes its speed, causing the wave to change direction. A common example is the bending of light as it passes from air into water, causing objects under water to appear displaced or “broken.” The amount of bending depends on the angle of the incoming wave and the refractive indices of the two media. - Absorption:
Absorption happens when the energy of a wave is taken in by the material it encounters, usually converting the wave’s energy into heat. For example, when sunlight hits a dark object, much of the energy is absorbed by the object, causing it to warm up. This is why dark materials, like black clothing or asphalt, absorb more light and heat compared to lighter materials. - Transmission:
Transmission is the passing of a wave through a material or object without being absorbed or reflected. Light passing through glass or sound passing through air are examples of transmission. In this case, the wave continues to propagate through the material, though it may lose some energy depending on the medium’s properties.
