The process you're fishing for is "polarization", but that's a
misleading description.
Polarization doesn't do anything to change the light waves.
It simply filters out (absorbs, as with a polarizing filter) the
light waves that aren't vibrating in the desired plane, and
allows only those that are to pass.
The intensity of a light beam is always reduced after
polarizing it, because much (most) of the original light
has been removed.
A laser light source may be thought of as an exception,
since everything coming out of the laser is polarized.
Answer:
26.67 m/s
Explanation:
From the law of conservation of linear momentum, the initial sum of momentum equals the final sum.
p=mv where p is momentum, m is the mass of object and v is the speed of the object
Initial momentum
The initial momentum will be that of basketball and volleyball, Since basketball is initially at rest, its initial velocity is zero

Final momentum

It goes through the holes in the cup .
Answer:

Explanation:
Using the given equation, we calculate the energy associated with the excited state
and 

Helium has an atomic number (Z) equal to 2, for n=8:

For n=4:

When an electron jumps from an energy level with greater energy
to one with lower energy
the wavelength of the emitted photon is given by:

h is the Planck constant and c the speed of light in vaccum. So, we have:
