what is diffraction of light?
Diffraction of light is the bending and spreading of light waves when they pass through a narrow opening or around the edge of an obstacle.
This phenomenon occurs because light behaves as a wave. Diffraction is more noticeable when the size of the obstacle or opening is comparable to the wavelength of light.
Examples of Diffraction:
Light spreading after passing through a narrow slit.
Coloured patterns seen on a CD or DVD.
Slight bending of light around sharp edges.
Key Characteristics:
Demonstrates the wave nature of light.
Causes light to spread beyond the geometric shadow region.
Becomes more significant for smaller openings.
In simple terms: Diffraction of light is the spreading or bending of light waves around obstacles or through narrow openings.
