The wavelengths associated with gems and planets typically refer to the colors they appear as or the frequencies of light they reflect or emit. Here are some examples:
1. Gems:
Ruby: Red color, typically with wavelengths around 620-750 nm.
Emerald: Green color, wavelengths around 490-570 nm.
Sapphire: Blue color, wavelengths around 450-495 nm.
Diamond: While colorless, it refracts light across various wavelengths.
2. Planets:
Mercury: Appears reddish-orange due to its surface composition.
Venus: Appears yellowish due to its thick clouds reflecting sunlight.
Mars: Appears reddish due to iron oxide (rust) on its surface.
Jupiter: Exhibits various bands of colors in its atmosphere due to different chemical compositions.
Saturn: Similar to Jupiter, shows atmospheric bands and rings that reflect and refract light in various wavelengths.
Uranus and Neptune: Both have bluish appearances, attributed to methane in their atmospheres absorbing red light.
