Activity 5.3 Light Phenomena Define the following light phenomena 1. Halo 2. Sundog 3. Rainbow 4. Reflection 5. Mirage​

Sagot :

Answer:

  1. Halo, any of a wide range of atmospheric optical phenomena that result when the Sun or Moon shines through thin clouds composed of ice crystals. These phenomena may be due to the refraction of light that passes through the crystals, or the reflection of light from crystal faces, or a combination of both effects.
  2. Sun dog, also called mock sun or parhelion, atmospheric optical phenomenon appearing in the sky as luminous spots 22° on each side of the Sun and at the same elevation as the Sun. Usually, the edges closest to the Sun will appear reddish
  3. rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun.
  4. reflection is the phenomenon when light is returned after impinging on a surface. To accept reflection we must accept the wave nature of light, because reflection has to do with waves. Part of light wave or whole the wave remains at the same medium after the reflection.
  5. A mirage is a naturally occurring optical phenomenon in which light rays bend via refraction to produce a displaced image of distant objects or the sky. The word comes to English via the French (se) mirer, from the Latin mirari, meaning "to look at, to wonder at".
