think of a wall in the water with a gap in the middle. waves come straight at the wall but as the waves go through the gap they bend. this is called diffraction.
When waves strike a barrier with a gap, they diffract or spread out as they pass through the gap. This diffraction causes the waves to bend around the edges of the gap, creating a pattern of interference on the other side of the barrier. The size of the gap relative to the wavelength of the waves will determine the extent of diffraction.
A wider gap will lead to more spread out waves when water waves pass through a gap in a barrier. This is because wider gaps allow more wave energy to pass through, resulting in greater wave diffraction and spreading out of the waves after passing through the gap.
Maximum diffraction occurs when the size of the diffracting opening or obstacle is comparable in size to the wavelength of the wave passing through it. This condition allows for the most bending or spreading of the wave, resulting in a more pronounced diffraction pattern.
Diffraction is the name given to the tendency for waves to spread out when they meet a gap in a barrier. This phenomenon occurs when waves encounter an obstacle or pass through an aperture, causing them to bend and spread out.
Well, darling, that would be good ol' refraction at play. When light enters through a gap in the curtains, it bends and spreads out, creating a stream of light that we can see. It's like nature's way of saying, "Hey, look at me, I'm here to brighten up your day!"
Bends and spreads out.When waves of any kind, sound, light electromagnetic radiation hit a gap in a barrier that is on the same scale as the wavelength then diffraction will occur. Diffraction is the bending of the wave and this appears as circular waves when we observe this effect with water.A common diffraction grating can be seen on a CD or DVD. The light spreads and we see this as different colours.

When gap size is equal to wavelength
When the gap becomes smaller than the wavelength of the incident wave, the wave diffraction increases significantly. The wave spreads out more as it passes through the narrow opening, leading to pronounced interference patterns. This results in phenomena such as the formation of multiple maxima and minima on a screen, demonstrating the wave-like behavior of particles, as seen in experiments like the double-slit experiment. Consequently, the dot may appear less defined and more spread out due to this diffraction effect.
