The energy of the red light emitted by a neon atom is 2.827*10^-19J
Light produces photons which might be small packets of power. as the atoms of an object are heated, it results within the manufacturing of photons. The electrons locate pleasure from the warmth and produce extra energy. This power emits inside the shape of a photon, and extra photons are released because the cloth becomes hotter.
The SI unit of wavelength is metre typically denoted as m. at the same time as measuring wavelength the multiples or fractions of a metre is also used. extensively, exponential powers of 10 are used while wavelengths are of a huge property. while there are shorter wavelengths they're expressed as negative exponential.
c=3*10^8 h=6.626*10^-34
wavelength= 703.2*10^-9m
E=2.827*10^-19J
Hence energy of the red light is 2.827*10^-19J.
