Question

a) When multiple wavelengths are emitted from a source and seen by your eyes, your brain perceives a single color as a blend of the individual emitted wavelengths. If wavelengths of 550, 600, and 650 nm are being emitted in a bright line spectrum of a hot gas, what color would be seen by your eyes?

b) Select the one response that correctly completes the statement: For an emission of 650 nm, the electron energy levels of the transition are:

1) higher in energy than the energy levels of a 550 nm transition.

2) lower in energy than the energy levels of a 550 nm transition.

3) separated by a difference greater than those of a 550 nm transition.

4) separated by a difference less than those of a 550 nm transition.

Explanation / Answer

a) multiple wavelengths 550, 600 and 650 nm blend would give a color as,

Orange

b) For an emission of 650 nm, the energy levels of the transiitons are,

2) lower in energy than the energy levels of a 550 nm transition.

energy and wavelength are inversely proportional to each other.
