Detailed Solution

The above statement is True.
Rainbows consist of seven colours because water droplets work like a prism and split white sunlight into seven colours of the spectrum (red, orange, yellow, green, blue, indigo, violet). Thus, seven colours in the spectrum VIBGYOR are in the correct sequence. Since Violet colour has a shorter wavelength, it bends the most, followed by Indigo and so on.
