What determines how much a wave diffracts when it encounters an opening or obstacle?
The diffraction of a wave when encountering an opening or obstacle is determined by the wavelength of the wave and the size of the opening or obstacle. Generally, waves with longer wavelengths diffract more when encountering obstacles or passing through small openings. The amount of diffraction also depends on the shape and dimensions of the obstacle or opening.
Does a wave travels trough a hole in a barrier it bends?
Yes, when a wave encounters a small opening in a barrier, it can diffract, which causes it to bend around the edges of the hole and spread out on the other side. This phenomenon is a characteristic of wave behavior known as diffraction.
Is diffraction more pronounced through a small or a large opening?
Diffraction is more pronounced through a small opening because the smaller the opening, the higher the amount of bending or spreading of light waves as they pass through. This phenomenon is more noticeable when the opening size is close to the wavelength of the light being diffracted.
How does the size of a barrier or opening affect the amount of diffraction of a wave?
Huygen's Principle tells us that, at each point that a propagating wave reaches, a spherical wave emanates outwards from that point. When we're looking at a plane wave propagating (without a collision), the spherical emanations from each point on the wave front cancel out in all but the forward propagation direction, which is why a plane wave continues to travel as a plane wave. When a wave strikes a barrier with a tiny opening in it, on the other side of the opening you can expect to see waves propagating outward radially from the opening. When the opening is wider, the spherical waves coming from the points towards the center of the opening nearly cancel out, but at the edges of the opening there isn't anything to cancel out with, so if you're not in line with the opening (as in, if you look at the nearest point in the opening, your line of sight is not perpendicular to the original wavefront), you will see the wavefront coming radially from the opening edge nearest you. The closer you are (angularly) to being in front of the opening, the more plane-like the wave will be. It is because of this same diffraction that we see an interference pattern when there are two small openings in the barrier. In this case, the radial waves will constructively and destructively interfere at different points beyond the barrier.
The bending of a wave around a barrier or an opening?
This phenomenon is called diffraction. When a wave encounters an obstacle or an aperture that is of similar size to the wavelength of the wave, diffraction occurs, causing the wave to bend around the obstacle or spread out after passing through the opening. This effect is a result of the wave interfering with itself as it encounters the obstacle or opening.
What happens when a large wave travels through a small opening?
The wave diffracts and behaves like the opening is a point source.
Does a wave diffacts more if its wavelength is small copared to the size of a opening or obstacle?
yes

What happens if you wave at the northern lights?
Nothing happens if you wave at them.
The bending of a wave around a barrier or an opening?
This phenomenon is called diffraction.

This effect is a result of the wave interfering with itself as it encounters the obstacle or opening.
How can diffraction occur in water and can you explain the process in detail?
Diffraction can occur in water when waves encounter an obstacle or pass through a narrow opening. This phenomenon happens because water waves, like light waves, can bend around obstacles or spread out when passing through a small opening. When a wave encounters an obstacle or opening, it causes the wave to change direction and spread out, creating a diffraction pattern. This process is similar to how light waves diffract when passing through a narrow slit, creating patterns of light and dark bands.
What happens when a wave moves from one medium into another of different densities?
When a wave moves from one medium into another of different densities, it changes speed and direction due to the change in propagation velocity. This phenomenon is known as refraction. The wave can either bend towards the normal (if entering a more dense medium) or away from the normal (if entering a less dense medium).
When a wave moves throgh an opening in a barrier?
When a wave moves through an opening in a barrier, it diffracts, spreading out into the region beyond the barrier. This diffraction phenomenon occurs because the wave bends around the edges of the barrier, resulting in a curved wavefront. The extent of diffraction depends on the size of the opening and the wavelength of the wave.
