Continue readingOil is a nonpolar liquid, meaning its molecules do not have a net electric charge. Because of this, it does not interact with light in the same way that polar substances do. Instead, oil scatters light in a way that creates a shimmering or iridescent effect. The refractive index of oil is lower than that […]
Continue readingThe properties of light, such as refraction, diffraction, and reflection, impart particular characteristics to light. But these same properties can also be harnessed for other purposes, such as fun optical effects or more practical applications like eyeglasses. One common lens type that uses these properties is the diffraction grating lens or light diffraction glasses. These […]
Continue readingConstellations and asterisms are both groups of stars, but there is a minor difference between them. However, before the 20th century, these terms were used interchangeably for star patterns. The International Astronomical Union (IAU)1 adopted 88 modern constellation boundaries in the 1920s. After that, constellations became specific star areas in the celestial sphere. On the […]
