Diffraction and Mountain Profile

Explanation:

Diffraction is the bending of waves around obstacles or through openings. When light waves encounter an obstacle, they bend around it and spread out, creating a diffraction pattern. The luminous border that surrounds the profile of a mountain just before the sun rises behind it is an example of diffraction.

Mountain Profile:

The profile of a mountain refers to the outline or shape of the mountain as seen from a particular perspective. Mountains can block the path of light waves, causing them to diffract around the mountain and create a luminous border.

Diffraction Phenomenon:

The phenomenon of diffraction occurs when the wavelength of the wave is comparable to the size of the obstacle or opening it encounters. In the case of the luminous border around the mountain profile, the size of the mountain is comparable to the wavelength of visible light. Therefore, when light waves encounter the mountain, they bend around it and spread out, creating the luminous border.

Conclusion:

In conclusion, the luminous border that surrounds the profile of a mountain just before the sun rises behind it is an example of diffraction. When light waves encounter the mountain, they bend around it and spread out, creating a diffraction pattern that results in the luminous border.
