Find the Initial and Final states of an excited Hydrogen Atom

AI Thread Summary
A hydrogen atom in an excited state absorbs a photon with a wavelength of 434 nm, prompting the need to determine its initial and final energy states. The relevant equation is 1/λ = 1/91.127 * (1/nf² - 1/ni²), which relates the wavelength to the principal quantum numbers of the initial and final states. The attempt to solve the equation reveals two unknowns (ni and nf) with only one equation available, complicating the solution. Further exploration of the hydrogen spectrum may provide insights into possible transitions. Understanding the energy levels of hydrogen is crucial for accurately identifying the initial and final states.

Homework Statement


A hydrogen atom in an excited state absorbs a photon of wavelength 434 nm. What were the initial and final states of the hydrogen atom?

Homework Equations



1/λ=1/91.127 * (1/nf2-1/ni2)

The Attempt at a Solution



Tried to use the equation, but keeping the initial and final n's as just 1/n2. can find a value for n2, but still have two unknowns (initial and final n level) and only the one equation

Thread 'Rolling without slipping on a curved surface'

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 .

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...
