A beam of ultraviolet light of all wavelengths 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. Then,

some of the incident wavelengths will be absent in
