Detailed explanation-1: -Hyperspectral data sets are generally composed of about 100 to 200 spectral bands of relatively narrow bandwidths (5-10 nm), whereas, multispectral data sets are usually composed of about 5 to 10 bands of relatively large bandwidths (70-400 nm).
Detailed explanation-2: -[remote sensing] A wavelength range in the spectrum of reflected or radiated electromagnetic (EM) energy to which a remote sensor is sensitive. Red, green, and blue are spectral bands used by a digital camera; the red band, for example, collects light from approximately 625-740 nanometers.
Detailed explanation-3: -The Landsat system covers 7 spectral bands (of which six are shown here) while the Hyperion instrument records data in 220 bands from 353 nanometers to 2577 nanometers.
