As the wavelength increases, what happens to the degree of diffraction?

When considering the relationship between wavelength and diffraction, it is important to understand the principles of wave behavior. Diffraction refers to the bending and spreading of waves as they encounter obstacles or openings. This phenomenon is influenced by the wavelength of the wave relative to the size of the obstacle or the opening.

As the wavelength increases, the degree of diffraction also increases. This is because longer wavelengths are more likely to bend around obstacles or spread out when passing through openings. The diffuse spreading of waves occurs more prominently with larger wavelengths, making it easier for them to navigate around barriers compared to shorter wavelengths.

For instance, sound waves, which can have relatively long wavelengths, can bend around objects and fill a room more effectively than light waves, which have much shorter wavelengths. This increased diffraction with longer wavelengths is observable in various scenarios, such as in acoustics or in the behavior of water waves interacting with obstacles.

Therefore, the correct answer indicates that as wavelengths increase, diffraction becomes more pronounced, leading to a greater degree of spreading and bending of the waves.
