Decreasing the distance between the wave sources....

AI Thread Summary
Decreasing the distance between two wave sources will enlarge the interference pattern, resulting in larger diffraction and greater angles between nodal lines. This change also leads to a decrease in the wavelength of the resulting waves. The discussion highlights the challenge of visualizing these concepts, with participants expressing a desire for simulations to better understand the effects. Confidence in the correctness of the answer varies among contributors, with some affirming that a decrease in distance correlates with a decrease in wavelength. Overall, the conversation centers on clarifying the impact of source distance on wave interference patterns.

Homework Statement


Imagine a interference pattern like the common water-wave interference pattern.

What effect would decreasing the distance between the 2 wave sources have on the interference pattern?

Homework Equations

The Attempt at a Solution


A change in the distance between the two sources will also alter the number of lines. When the distance is decreased between the wave sources the interference pattern will become larger ( larger diffraction ) and the angles between the nodal lines would become greater, and the wavelength of the resulting waves would also decrease.

I'm not very confident in my answer. I tried to visualize this in my mind but it was difficult. I tried to look for some ripple simulations to help me but I couldn't find one.

Is my answer correct? I tried to visualize it but I just couldn't. I just took examples from my book and compared them.

I'm I missing anything important or am I wrong? Thank you in advanced.

I think you are correct i.e. the wavelength will decrease.
If they are brought closer then the distance will decrease and so, perhaps the wavelength will decrease.
Mind you, this is only a supposition.
 
Hmm is there anything else I can add/ know of a simulator that can prove my statement?

Sorry I'm a bit of perfectionist.

Thank you for the help too.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
