10Dispersion occurs because different colors of light travel at different speeds in a medium.
Red light deviates more than violet light in a prism.
Violet light has the shortest wavelength in the visible spectrum.
Newton's disc demonstrates recombination of colors into white light.
Water droplets in the atmosphere act as tiny prisms to form rainbows.
A rainbow is circular but appears semicircular from the ground.
The seven colors in VIBGYOR are equally spaced in wavelength.
The speed of light is the same for all colors in a medium other than vacuum.
The visible spectrum is created only by refraction of light through a prism.
Indigo light falls between blue and violet in VIBGYOR.
Percentage: 0%
