What is absorption spectrum?

Give an example for continuous spectrum.

…………is an example for continuous spectrum.

Deltalambda is the difference between the wavelength of K_(alpha) line and the minimum wavelength of the continuous X-rays spectrum when the X-ray tube is operated at a voltage V. If the operating voltage is changed to V/3 , the above difference is Deltalambda Then,

A certain transition in H spectrum from an excited state to ground state in one or more steps gives rise to total 10 lines. How many of these belong to uv spectrum?

Assertion (A) : Emission or absorption of light, spectrum is a collection of a group of wavelengths. Reason ®: Electromagnetic energy can be gained or lost in discrete values and not in a continuous manner.

How many Balmer lines in the spectrum will be observed when electrons return from 7^(th) shell to 2^(nd) shell ?
