Step-by-Step Analysis
The question asks which processes occur only when absorbing photons with energy higher than visible light.
Option 1: ionization (loss of an electron) – Ionization requires enough energy to overcome the electrostatic attraction of the nucleus on the electron, which is typically much larger than visible photons. Thus, high-energy (ultraviolet or higher) photons are needed......Login to view full explanationLog in for full answers

Question at position 11 Humans are warned to shield their eyes from ultraviolet radiation with wavelengths shorter than 300 nm but not from infrared radiation with wavelengths of about 900 nm. Which of the following explains the reason for this based on what happens at the molecular level with exposure to these types of radiation?300 nm radiation has one-third the energy of 900 nm radiation, so ultraviolet radiation is more likely to cause molecular vibration to occur.300 nm radiation has triple the energy of 900 nm radiation, so ultraviolet radiation is more likely to promote electrons or break covalent bonds.900 nm radiation has one-third the energy of 300 nm radiation, so infrared radiation is more likely to cause molecular rotation to occur.900 nm radiation has triple the energy of 300 nm radiation, so infrared radiation is more likely to promote electrons to break covalent bonds.
