The fact that sky appears to be blue is due to _______________.

Rayleigh scattering occurs when particle size is ______________than wavelength of incoming radiation.

Dust, smoke or pollen exhibits ________________ scattering.

_____________ scattering occurs when the particle size is nearly 8 - 10 times than that of wavelength of incoming radiation.

Those areas of the spectrum which are not severely influenced by atmospheric absorption and thus, are useful to remote sensors, are called ___________________.

Transmission Windows in visible and Infrared regions are ______________ µm.

In wavelength from __________ μm clouds and snow have same reflectance and hence difficult to differentiate.
