Question

The wavelengths of light emitted by an atom:

are identical to those absorbed by that atom.

vary depending upon the wavelength selector in the emission experiment.

are longer than those absorbed by that atom.

are shorter than those absorbed by that atom.

When an atom or molecule emits light:

it absorbs heat from the surroundings.

it changes color.

a transition from a higher energy level to a lower energy level occurs.

a transition from a lower energy level to a higher energy level occurs.

are identical to those absorbed by that atom.

vary depending upon the wavelength selector in the emission experiment.

are longer than those absorbed by that atom.

are shorter than those absorbed by that atom.

1. Option B, depends on material which is considered in experiment

2. C, emission of light involves transition from upper energy level to lower energy level.
