Monochromatic light from a point source is directed toward the sharp edge of a solid object. how does diffraction change the image that appears on a screen beyond the object?

why are diffraction patterns not commonly observed in everyday situations?

Monochromatic light from a point source is directed toward the sharp edge of a solid object.

Explanation:

When a monochromatic light from a point source is directed toward the sharp edge of a solid object, the light beam will get diffracted from the edge as the body of the solid object will not be passing the light. So the incident light will occur as a spots on the screen beyond the object after diffraction.

Diffraction of light occurs when the incident light falls on a grater and the width of the grater or the obstructing object should be comparable or lesser to the size of the wavelength. So, in everyday situations we do not observe diffraction patterns as the obstructing objects in real world.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
