Number of Nodal Lines in Two-Point Interference Pattern

AI Thread Summary
In a two-point interference pattern, increasing the wavelength of the sources leads to an increase in the number of nodal lines. This occurs because a longer wavelength results in a lower frequency, which allows for more opportunities for destructive interference. As the wavelength increases, the spacing between nodal lines also increases, creating more distinct nodal lines in the pattern. The relationship between wavelength and nodal lines is crucial for understanding interference phenomena. Thus, longer wavelengths contribute to a greater number of nodal lines in the interference pattern.

Homework Statement



In a two - point in phase inteference pattern, what will happen to the number of nodal lines if the wavelength of the two sources increases? Justify your answer


Homework Equations



Not too sure if an equation is needed to answer this question

The Attempt at a Solution



I said they would stay the same but its wrong.

as the wavelength increases there will be more more nodal lines as the frequency will also increase. with faster wavelenghts the frequency will increase which means the waves will be shorter which will allow for more destructive interference which are nodal lines.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
