Actually, diffraction occurs all the time. But when the aperture/wavelength ratio is large, the spacing between fringes becomes too small, and the diffractive effects are unnoticeable.

Understanding Light Diffraction
Light diffraction is the bending and spreading of waves around obstacles and openings. It is a fundamental phenomenon observed in wave behavior.
Why Option A is Correct
The correct answer is option 'A': "The wavelength of the visible range is small." Here’s why:
Conclusion
In summary, the visibility of light diffraction is significantly affected by the relationship between the wavelength of light and the size of objects. A small wavelength relative to the size of obstacles leads to minimal diffraction effects, making this phenomenon less noticeable in everyday observations.
Light diffraction is the bending and spreading of waves around obstacles and openings. It is a fundamental phenomenon observed in wave behavior.
Why Option A is Correct
The correct answer is option 'A': "The wavelength of the visible range is small." Here’s why:
- Wavelength and Diffraction: Light waves in the visible spectrum have wavelengths ranging from approximately 400 to 700 nanometers. When the size of the obstacle or slit is comparable to or larger than the wavelength, diffraction is observable. However, if the wavelength is small relative to the size of the object, diffraction effects become negligible.
- Small Wavelength: A smaller wavelength means that the light waves will not spread out significantly when encountering most ordinary objects. This results in minimal diffraction effects, making it difficult to notice the phenomenon without specialized equipment.
- Comparison with Other Options:
- B: Light waves being transverse and longitudinal does not directly influence the visibility of diffraction.
- C: The size of ordinary objects being small does not necessarily mean diffraction is less noticeable; it depends on the wavelength.
- D: While apparatus can enhance the observation of diffraction, the fundamental visibility issue is tied to wavelength size.
Conclusion
In summary, the visibility of light diffraction is significantly affected by the relationship between the wavelength of light and the size of objects. A small wavelength relative to the size of obstacles leads to minimal diffraction effects, making this phenomenon less noticeable in everyday observations.
