Is diffraction more pronounced through a small or a large opening?
A smaller opening because it is harder for a wave to travel through smaller openings so after passing through it will diffract more.
What happens when a sound wave hits a small thin membrane?
The membrane (such as you eardrum) vibrates.
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.
What happens to the wavelength of a wave when the frequency of the wave is doubled but the wave speed stays the same?
Nothing happens
What do diffraction and refraction have in common?
They both involve light bending. Refraction is where light bends because of entering a denser (or less dense) medium, so it slows and changes direction, moving towards the "normal" if it is entering a more dense medium and away from the "normal" when entering a less dense medium. The normal is a perpendicular imaginary line from the medium.Diffraction involves any wave bending as it hits a corner. An example is light being seen through fog or clouds where light fringes of light and dark bands are produced. this happens to any wave.So the similarities are that they both involve light bending. Hope that answers your question!For GENERAL WAVES:Refraction is the bending of a wave as it enters a new medium at an angle. When a wave enters a medium at an angle, refraction occurs because one side of the wave moves more slowly than the other side (one side needs to cover more distance = faster while other side needs to cover less distance = slower speed)Diffraction is the bending of a wave as it moves around an obstacle or passes through a narrow opening. A wave diffracts more if its wavelength is large compared to the size of an opening or obstacle.
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
Is diffraction more pronounced through a small or a large opening?
A smaller opening because it is harder for a wave to travel through smaller openings so after passing through it will diffract more.
What happens to a wave when it passes an edge or an opening?
It undergoes diffraction. Please see the related link for more information.

The membrane (such as you eardrum) vibrates.

What happens if you wave at the northern lights?
Nothing happens if you wave at them.
What happens to the wavelength of a wave when the frequency of the wave is doubled but the wave speed stays the same?
Nothing happens
What should i do if a guy always stares at you?
try smiling or a small wave and see what happens if you get no response write him off as a creeper.
