AI Thread Summary
To compute the highest energy photon in the hydrogen spectral series, one must first recognize that the highest energy corresponds to the shortest wavelength. The relationship between energy and wavelength is defined by Planck's equation, E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. After calculating the shortest wavelengths for the Lyman, Balmer, Paschen, and Bracket series, the corresponding energies can be derived using this formula. Understanding this relationship is crucial for solving the problem effectively. The discussion emphasizes the importance of linking wavelength and energy in spectral analysis.

hi,

i have a question...
i was asked to compute the shortest wavelength in each of these hydrogen spectral series: Lyman, Balmer, Paschen and Bracket - which i did...

in the second part i need to compute the energy (in electron volts) of the highest energy photon produced in each series.

my problem is with the second part...

can anyone please help ?

Interesting, I would expect the second part to come first.

The highest energy photon has the shortest wavelength; you're being asked for the same photons. You need the relationship between wavelength and energy (featuring Plank's constant).
 
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 .
