Answer 2

Amplitude frequency and wavelength are all related so is it b?

Answer 3

do you the answer?

Answer 4

Frequency and wavelength are related, you can't change one without the other as long as the speed of your wave is a constant.

Amplitude is the intensity of a wave, for water waves this is the height. You could have two waves with exactly the same wavelength and different heights for instance.

The slit width is a big deal when it comes to waves, since a single wave hitting a single slit will diffract as long as it's small enough, I'm sure there are some cool demonstrations of this on youtube. For instance when you see stuff with your eyes, there's no diffraction going on, but when light shines off of a CD it's cause of a similar effect, the grooves in the CD are about the same length as the light's wavelengths which causes them to diffract in a similar way. So you have had some experiences with which to relate this to at least, I'm sure there are more.

I dunno about the "distance between the source and slit" thing. I'm gonna have to say that has no effect but not sure. I know you can diffract sunlight but that's so huge and so far away not sure if that counts or what, also depends on what kind of waves we're talking about. If the wave die off before they reach the slit, like say sound waves.

@Kainui thanks a lot its make sence
