1. d
Violet has the most energy among all the colors of rainbow.
2. b
red light has very long wavelength, and therefore has less energy.
3. b
Rainbows are formed by the dispersion of light & reflection (not total internal reflection) from drops of water. The rainbow color sequence can be analyzed by drawing a ray diagram of the refraction of sunlight inside water drops.
4. C
red light has very long wavelength, and therefore has less energy.
5. C
ROY-G-BIV is the acronym that represents all of the colors in the visible spectrum of light
6. b
Visible light, also known as white light, consists of a collection of component colors. ... Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue and violet. The separation of visible light into its different colors is known as dispersion.
7. C
Violet - shortest wavelength, around 400-420 nanometers with highest frequency. ...
Indigo - 420 - 440 nm.
Blue - 440 - 490 nm.
Green - 490 - 570 nm.
Yellow - 570 - 585 nm.
Orange - 585 - 620 nm.
Red - longest wavelength, at around 620 - 780 nanometers with lowest frequency
