Chapter 5.1, Problem 10SSC

Interpretation Introduction

Interpretation:

The continuous and emission spectrum needs to be compared.

Concept introduction:

The white light is composed of seven different colors which have different wavelength. The spectrum of light can be defined as the range of different colors which forms when light is passed through prism.

Answer to Problem 10SSC

Both spectrums that is continuous and emission are related to transitions but the appearance is different in both cases.

As in the emission spectrum the coloured lines are overserved against a black background whereas in a continuous spectrum the colourful bands are observed.

Continuous spectrum consists of all wavelength whereas emission spectrum consists of few wavelength only.

Explanation of Solution

The spectrum which has all wavelengths continuous without any gaps over a wide range is called as continuous spectrum. Such type of spectrums are commonly observed by solids at high temperature.

On the contrary, the movement of electron from an excited state to the ground energy level emits a certain amount of energy as photons. The spectrum of this transition consists of lines of black background called emission spectrum. Emission spectrum appears in the form of lines.

So overall both spectrums are related to transitions but the appearance is different in both cases.

As in the emission spectrum the coloured lines are overserved against a black background whereas in a continuous spectrum the colourful bands are observed.

Conclusion

Both spectrums are related to transitions but the appearance is different in both cases.

As in the emission spectrum the coloured lines are overserved against a black background whereas in a continuous spectrum the colourful bands are observed.
