If Wavelength is 363X10^-9m Find the frequency

Given parameters:

Wavelength = 363 x 10⁻⁹m

Unknown:

Frequency  = ?

The frequency of a wave is the number of waves passing through a point per unit of time.

In the electromagnetic spectrum, to find wave frequency, we use the expression below;

          V  = f π

where V is the wave velocity

f is the wave frequency

π is the wavelength

Often times, we use the velocity of light = 3 x 10⁸m/s

Now input the parameters and solve for f;

  3 x 10⁸m/s   =  f x  363 x 10⁻⁹m

     f  =   = 1.21 x 10⁻¹⁵Hz

The frequency of the wave is 1.21 x 10⁻¹⁵Hz

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
