What is emission spectrum?

What is emission test?

(A) : During solar eclipse, the solar spectrum is an emission spectrum ( R) : During solar eclipse, the radiation from the elements in chromosphere is only received on earth.

What is visible spectrum ? What is its wavelength range ?

(A) Its is not possible that all the lines avail-able in the emission spectrum will also be available in the absorption spectrum (R) The spectrum of hydrgen atom is only absorption spectrum

(A) Hydrogen atom consists of only one electron but its emission spectrum has many lines. (R) Only Lyman series is found in the absorption spectrum of hydrogen atom whereas in the emission spectrum, all the series are found.

Which of the following transitions are allowed in the normal electronic emission spectrum of an atom?

Atomic hydrogen is excited from the grounds state to the n^(th) state. The number of lines in the emission spectrum will be:
