| Colour vision in humans and honeybees is restricted to brighter light intensities than those accessible to nocturnal hawkmoths. |
| Figure 1 is an isoseismal map of the earthquake zone, showing the distribution of intensities of shaking, with contours of equal intensity. |
| The relative intensities were either estimated or measured using a device that determined the darkness of the spots called a densitometer. |
| Initial operation involved low beam intensities, and these runs failed to produce W or Z particles. |
| Measured stomatal conductance vs. calculated stomatal conductance index under changing light intensities. |
| Note that the spectral intensities have been normalized relative to sample weight. |
