* Diffraction and Wavelength: Diffraction is the bending of waves around obstacles or through openings. The amount of diffraction depends on the wavelength of the wave compared to the size of the obstacle or opening.

* Frequency and Wavelength: Frequency and wavelength are inversely proportional. This means that as frequency increases, wavelength decreases.

* The Relationship: Since diffraction is more pronounced when the wavelength is larger than the obstacle/opening, as frequency increases and wavelength decreases, diffraction becomes less noticeable.

Example:

* Sound Waves: Low-frequency sound waves (like bass) diffract more easily around obstacles, which is why you can hear bass music from further away. High-frequency sound waves (like treble) diffract less, which is why you might not hear the high notes as well from a distance.

* Light Waves: Red light has a longer wavelength than blue light. This is why red light diffracts more than blue light, and you can see the red light bending more around corners.

In summary: Higher frequency means shorter wavelength, which in turn leads to less diffraction.
