Answer:
The Balmer series refers to the spectral lines of hydrogen, associated to the emission of photons when an electron in the hydrogen atom jumps from a level to the level
.
The wavelength associated to each spectral line of the Balmer series is given by:
where is the Rydberg constant for hydrogen, and where
is the initial level of the electron that jumps to the level n = 2.
The first few spectral lines associated to this series are withing the visible part of the electromagnetic spectrum, and their wavelengths are:
656 nm (red, corresponding to the transition )
486 nm (green, )
434 nm (blue, )
410 nm (violet, )
All the following lines lie in the ultraviolet part of the spectrum. The limit of the Balmer series, corresponding to the transition , is at 364.6 nm.
- Coefficient of static friction = 0.5
- Coefficient of Kinetic friction = 0.3
- Angular velocity = 500 RPMs
Let R be the radius of cylinder
The angular velocity is 500 RPMs
The normal force
Since the radius is very little for two block to execute circular motion so system will slide down.
