Abstract

From the general people perspective, sunrise and sunset are often associated with myths that have been rooted in society. The research aims to scientifically discuss the colour differences of the sky due to the apparent daily movement of the Sun. The discussion is related to the concept of Rayleigh Scattering, scattering of electromagnetic waves from Sun by the Earth^s atmosphere, using Photovoice techniques. The data was taken by taking pictures and analyzed by photovoice technique using various scientific sources. In the studies discussed in the article, the object used is photos of sky conditions at sunrise, during the day, and at sunset. The phenomena of the apparent daily motion of the Sun, which results in the transition of day and night, makes the colour of the sky appear different. These events occur due to the scattering of white light radiated by the Sun by particles of the Earth^s atmosphere. At dusk, the scattered light will pass through a further away path than during the day. This phenomenon causes the scattered light to be a large wavelength, namely red and orange. The blue colour does not appear at dusk because it has been scattered in areas that experience daylight.
