List of top Physics Questions on Electromagnetic Spectrum asked in AP EAMCET

Two bar magnets A and B are identical and arranged as shown. Their lengths are negligible compared to the separation between them. A magnetic needle placed between the magnets at point P gets deflected through an angle \( \theta \) under their influence. The ratio of distances \( d_1 \) and \( d_2 \) is: 


 

In the hydrogen spectrum, the difference in frequencies of first and second Lyman lines is equal to the frequency of the second Balmer line. This corresponds to:
A superconductor exhibits:
The ratio of de-Broglie wavelengths for the electron and proton moving with the same velocity is given as (m\(_e\): mass of electron, m\(_p\): mass of proton)
The ratio of the minimum wavelength of the Balmer series to the maximum wavelength in the Brackett series in the hydrogen spectrum is:
When a hydrogen atom emits a photon during a transition from $n = 4$ to $n = 2$, its recoil speed is about
