Which of the following correctly represents the sequence of colours observed on the screen when white light passes through a prism in its standard orientation?

Correct option is D

The correct answer is (d) VIBGYOR

Explanation:

• When a beam of white light passes through a standard glass prism, it undergoes dispersion and splits into its seven constituent spectral colours.
• Different colours of light bend through different defined angles with respect to the incident ray because they possess varying wavelengths.
• Red light possesses the longest wavelength and hence bends the least.
• Violet light possesses the shortest wavelength and hence bends the most.
• Because violet bends the most, it settles at the bottom of the visible spectrum, creating the sequence from bottom to top as Violet, Indigo, Blue, Green, Yellow, Orange, Red (VIBGYOR).

• The band of naturally ordered colours produced is known as a visible spectrum.
• The physical phenomenon of splitting white light into its component colours is explicitly called dispersion of light.
• Sir Isaac Newton was fundamentally the first scientist to comprehensively use a glass prism to obtain the spectrum of sunlight.

• This is entirely an arbitrary, incorrect scrambling of letters and does not represent any natural optical phenomenon.

• While this represents the colours, it lists them from top to bottom (least bent to most bent). In standard testing, reading up from the base of the prism gives VIBGYOR.

• This is just a jumbled string of the color acronym and has no physical meaning.
