Recap Condensation above the Earth surface produces  clouds. Clouds are divided into 4 main groups: High Middle Low Clouds with vertical development Satellites give a bird’s eye view of clouds. Geostationary satellites Polar-orbiting satellites Infrared images can provide a three-dimensional  view of the clouds: Height of the cloud an astronaut’s

Color The human eye is sensitive to the visible part of the electromagnetic spectrum ( λ =0.4-0.7  μ m): Intensity - light or dark; Wavelength – color. We see the objects because they  emit  and/or  interact with light  ( reflection transmission absorption refraction scattering diffraction Perception of color: Each color corresponds to a particular      wavelength. White: all wavelengths are present with      equal intensity; Black: no light is emitted and/or reflected     from the object.  Color of emitted light and temperature: The sun appears white.  Colder stars look redder ( λ max  is longer than  λ max  of the sun).  Hotter stars look bluer ( λ max  is shorter than  λ max  of the sun).
