Haze detection and characterisation by light scattering
... increased the most in Fig. 7.1 (blue light) followed by Fig. 7.2 (green light) then Fig. 7.3 (red light). From this, we can conclude that blue light scatters the most, then green, then red. Blue light has wavelength of range 450 to 495 nm whereas green light’s range is 495 to 570 nm, and red light’s ...

Astronomy 5682 Problem Set 6: Supernova Cosmology Due
... the flux of energy received from a source is equal to the luminosity of the source divided by 4π times the square of the distance. The luminosity is the rate at which the source releases energy, and it is independent of the source’s distance; it has units of energy/time (e.g., erg/s). The flux is th ...

As light waves travel along the surface of water, the boundary between air and water moves up and down, and tilts back and forth. The path of light leaving the water shifts as the boundary moves, causing objects ...
