Question

The spectrum produced by the white light by a prism is called
(a) pure spectrum
(b) impure spectrum
(c)monochromatic spectrum
(d) None of the above​

Answer 1

Option D is correct

None of the above​

The spectrum of frequencies of electromagnetic radiation released by an atom or molecule transitioning from a high energy state to a lower energy state is known as the emission spectrum of a chemical element or chemical compound. The energy difference between the two states is equal to the photon energy of the emitted photon. Each atom has a number of different electron transitions, each with a different energy difference. An emission spectrum is a collection of distinct transitions that lead to different radiated wavelengths. The emission spectra of each element is distinct. As a result, spectroscopy may be used to detect components in unknown substances.

Answer 2

Answer:

1. (d) None of the above. The Emission spectrum is produced by white light.

2. There are many ways in which continuous spectrum is produced such as when perfectly white light is incident on a prism.

3. A band of seven colors is seen or a rainbow produced in sunlight.

4. Whereas heating of gas produces an emission spectrum as the gas molecules absorb heat energy and emit it to the surrounding.
