An ambient standard is a never-exceed level for some pollutant in the ambient environment. For example, an ambient standard for dissolved oxygen in a particular river may be set at 3 parts per million (ppm), meaning that this is the lowest level of dissolved oxygen that is to be allowed in the river.
Emission standards are never-exceed levels applied directly to the quantities of emissions coming from pollution sources. Emission (or effluent) standards are normally expressed in terms of quantity of material per some unit of time - for example, grams per minute or tons per week. (Field, C. Barry and K. Martha, Environmental Economics: An Introduction, 2013, p. 207-208)
The lines are at the same frequencies
what is the difference between khadi and handloom
difference between tally & fact ?
There is no difference between a donkey and a burrow
There is no difference.
The California Camry has to meet lower emission standards.
NONE
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.

reflecttion is a part of incidentradiant but emission may be different of incident radiant.
no idea aye

Emission nebula glow and reflection nebula reflect the light form other stars
Emission is something be spread out, while absorption is something being taken in.
The acronyms are synonyms. AES = Atomic Emission Spectroscopy OES = Optical Emission spectroscopy
* emisssion of electron from the surface of the metal when light of suitable frequency falls-photoelectric emission. * emision of electron from the metal by quantum tunnling of electron.
