1
New cards
Whether or not a(n) rainbow appears is heavily dependent on
where the viewer is standing and where the sun is.
2
New cards
Sunlight is composed of
wavelengths of visible light, some being more bent than others when they enter and exit the water droplets.
3
New cards
When sunlight shines on the water droplets, it hits them at
42°.
4
New cards
Violet is seen on the bottom since it has
the shortest wavelength
5
New cards
The water droplets refractive index determines
the radius of the rainbow.
6
New cards
Antisolar point
________: the center of the circle of the rainbow, or an imaginary point exactly opposite the sun.
7
New cards
Rainbow
________: an optical phenomenon or illusion caused by both light reflection and refraction.
8
New cards
Rainbow
an optical phenomenon or illusion caused by both light reflection and refraction
9
New cards
Antisolar point
the center of the circle of the rainbow, or an imaginary point exactly opposite the sun
10
New cards
Double rainbow
occurs when light is reflected twice inside the water droplets
11
New cards
Red is seen on the top since
it has the longest wavelength.
12
New cards
The higher the refractive index of the water droplet,
the smaller the radius of the rainbow
13
New cards
The smaller the refractive index of the water droplet,
the larger the radius of the rainbow
