Answer published by the source. Consult the official source to check your work against its answer.

question

The promotion of an electron from the valence band into the conduction band in pure TIO2\mathrm{TIO}_2 by light absorption requires a wavelength of less than $350 \mathrm{~nm}$. Calculate the energy gap in electronvolts between the valence and conduction bands.
Plain-text mathematical notation (without MathML)
The promotion of an electron from the valence band into the conduction band in pure TIO₂ by light absorption requires a wavelength of less than $350 \mathrm{~nm}$. Calculate the energy gap in electronvolts between the valence and conduction bands.
Original LaTeX notation
