Which of the following utilize electromagnetic induction to operate?

1 answer:

7 0

The first two in a way use indiction. A generator causes an induced voltage on the output terminals by rotating a coil in a magnetic field (Faraday's Law of magnetic induction). A telephone microphone has a membrane that is excited (moved) by sound waves and on the back of this membrane is a magnet. The magnet is placed inside the core of a coil of wire that has a voltage induced in it by the changing magnetic flux through the loop as it vibrates.
A turbine is moved by fluids or air, and while they can drive generators they themselves do not require induction to operate

what is the necessary condition within the hydrogen atom for balmer line photons to be absorbed by the hydrogen atom

luda_lava [24]

Explanation :

When an electron jumps from one energy level to another, the energy of atom gets changed.

If a photon gets absorbed, the electron will move to higher energy levels and then fall back to the lower energy levels. Then each time a photon will be absorbed whose energy is given by difference between the initial and final energy levels i.e

In Balmer series, the transition is from higher energy levels to n = 2.

So, the necessary condition for Balmer series is that the electron should be at first excited state or n = 2 level as shown in figure.
