Atomic emission spectra

Each element emits specific colors of light that correspond to specific wavelengths.

two or more elements can have the same atomic emission spectra

When the input is white light from an incandescent bulb, the output is a few discrete lines. The pattern of the wavelengths of these lines is unique to hydrogen.

When the input is light from a hydrogen lamp, the output from the spectroscope is a continuous spectrum of all colours and visible wavelengths.

the model that explains atomic emission spectra is called Bohrs' Model

Different wavelengths, or distances between crests of waves, of light result in different colours of light.

The atomic emission spectrum is the pattern formed when light emitted by an element is separated into the different wavelengths it contains.
