If the wavelength of purple light is 400 x 10^-9 m, what is the frequency?
1 answer:
The frequency : a) 7.5 x 10¹⁴ /s
<h3>Further explanation</h3>Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves (/s or Hz)
f = c / λ
c = speed of light
= 3.10⁸ m/s
λ = wavelength
The wavelength(λ) of purple light is 400 x 10⁻⁹ m, so the frequency :

Answer:
Initially of nitrogen dioxide were in the container .
Explanation:
Volume of the container at low pressure and at room temperature =
Number of moles in the container =
After more addition of nitrogen gas at the same pressure and temperature.
Volume of the container after addition =
Number of moles in the container after addition=
Applying Avogadro's law:
(at constant pressure and temperature)
Initially of nitrogen dioxide were in the container .
