When white radiation is passed through a sample of hydrogen gas at room temperature , absorption lines are observed in lyman series only Explain

If radiation of all wavelengths from ultraviolet to infrared ispassed through hydrogen gas at room temperature absorption lines will be observed in the

A 12.5 eV electron beam is used to excite a gaseous hydrogen atom at room temperature. Determine the wavelengths and the corresponding series of the lines emitted.

A neutron beam, in which each neutron has same kinetic energy, is passed through a sample of hydrogen like gas (but not hydrogen) in ground state and at rest. Due to collision of neutrons with the ions of the gas, ions are excited and then they emit photons. Six spectral lines are obtained in which one of the lines is of wavelength (6200/51) nm.Which gas is this?

A beam of ultraviolet light of all wavelength passes through hydrogen gas at room temperature, in the x-direction. Assume that all photons emitted due to electron transitions inside the gas emerge in the y-direction. Let A and B denote the lights emerging from the gas in the x-and y-directions respectively. (i) Some of the incident wavelengths will be absent in A (ii) Only those wavelengths will be present in B which are absent in A (iii) B will contain some visible light (iv) B will contain some infrared light

Assertion (A): When hydrogen gas at high pressure and room temperature expands adiabatically into a region of low pressure, there is a decrease in temperature. Reason (R ) : Hydrogen gas at room temperature is above its inversion temperature.

What do you observe when hydrogen gas is passed through soap solution ?

A beam of light having wavelength distributed uniformly between 450 nmto 550 nm passes through a sample of hydrogen gas which wavelength will have the least intensity in the transition beam?

Draw the energy level diagram of hydrogen atom and show the transitions responsible for : (i) absorption lines of Lyman series. (ii) emission lines of Balmer series.

A 12.5 eV electron beam is used to bombard gaseous hydrogen at room temperature. Upto which energy. Level the hydrogen atoms would be excited ? Calculate the wavelengths of the first memeber of Lyman and first member of Balmer series.

When an electric current is passed through acidified water, 112 ml of hydrogen gas at N.T.P. is collected at the cathode in 965 seconds. The current passed, in amperes is:
