When the medium is unifrom, how do light waves travel though it?​

Chemistry
1 answer:
Sindrei [870]3 years ago
7 0

Answer:

Light waves travel in straight lines through a vacuum or a uniform medium. They vary only in wavelengths but they typically consist of periodic oscillations of both electric and magnetic fields. These are generated by charged particles that traverse through straight line in a vacuum.

How can the gravitational potential energy of an object be changed?
Aleksandr [31]

Answer:

Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).

In state n = 1, the energy of the hydrogen atom is -13.58 ev. what is its energy in state n = 2?
Gekata [30.6K]

The energy of a hydrogen atom in energy level n = 2 is 3.4 eV.

The ionization of energy of the hydrogen atom is 13.6 eV.

This is the minimum energy required to raise the electron from its ground state in the hydrogen atom.

n represents the Energy level.

When an electron changes from one energy level to another, the energy of the atom must change as well.  It requires energy to promote an electron from a lower energy level to a higher one.  This energy can be supplied by a photon whose energy E is given in terms of its frequency E = hf or wavelength E = hc/λ.

The formula for the energy of an atom is:

E = 13.6 * Z^{2} / n^{2}  .... this represents the allowed energy level in the hydrogen       atom

  = 13.6 * 1 / 2^{2}    since Z = 1 for hydrogen where Z is mass of atom

  = 13.6 / 4

  = 3.4 eV

The energy of a hydrogen atom in energy level n = 2 is 3.4 eV.

Balance the Chemical Equation. ITEM BANK: Move to Bottom 123456 C3H8 + O2 ⇒ H2O + CO2
stiks02 [169]

Answer:

Balanced chemical equation:

C₃H₈ + 5O₂    →     4H₂O + 3CO₂

Explanation:

Chemical equation:

C₃H₈ + O₂    →     H₂O + CO₂

Balanced chemical equation:

C₃H₈ + 5O₂    →     4H₂O + 3CO₂

1st step:

Left side                               Right side

C = 3                                      C = 1

H = 8                                     H = 2

O = 2                                     O = 3

2nd step:

C₃H₈ + O₂    →     H₂O + 3CO₂

Left side                               Right side

C = 3                                      C = 1×3 = 3

H = 8                                    H = 2

O = 2                                     O = 6+1 = 7

3rd step:

C₃H₈ + O₂    →     4H₂O + 3CO₂

Left side                               Right side

C = 3                                      C = 1×3 = 3

H = 8                                     H = 2×4 = 8

O = 2                                     O = 6+4 = 10

4th step:

C₃H₈ + 5O₂    →     4H₂O + 3CO₂

Left side                               Right side

C = 3                                      C = 1×3 = 3

H = 8                                     H = 2×4 = 8

O = 2×5= 10                          O = 6+4 = 10
