question

In 1879, Marie Cornu discovered that light from the Sun had a drop in ultraviolet (UV) light. Two years later, Walter Hartley found that ozone absorbs certain wavelengths of UV light. What motivated Charles Fabry and Henri Buisson to conduct research that led to the discovery of the ozone layer in the atmosphere of Earth?

choices

  • inquiring into the causes of observed phenomena
  • finding options for replacing missing wavelengths of light
  • health concerns about the effects of ultraviolet radiation
  • predicting future changes in ultraviolet light output
