Card 1Dispersion of Light

What is dispersion of light? Name the phenomenon that causes white light to split into its component colours when passing through a prism.

Answer

Dispersion of light is the phenomenon of splitting up of a composite light into its component colours. When white light passes through a prism, different colours deviate by different amounts due to th

Card 2Visible Spectrum

List the colours of the visible spectrum in order of increasing wavelength and their approximate wavelength ranges.

Answer

VIBGYOR - Violet (380-440 nm), Indigo (440-460 nm), Blue (460-500 nm), Green (500-570 nm), Yellow (570-590 nm), Orange (590-620 nm), Red (620-750 nm). Red has the longest wavelength and deviates least

Card 3Dispersion and Wavelength

Why does red light deviate least and violet light deviate most when passing through a prism?

Answer

The deviation of light through a prism depends on its wavelength and refractive index. Red light has the longest wavelength (620-750 nm) and lowest refractive index, so it deviates least. Violet light

Card 4Rainbow Formation

Explain how a rainbow is formed in nature. What three optical phenomena are involved?

Answer

A rainbow is formed by the combined effect of three optical phenomena: 1) Refraction - sunlight enters water droplets and bends, 2) Dispersion - white light splits into component colours inside the dr

Card 5Primary Colours

What are the three primary colours of light? What colour is produced when all three are combined in equal intensity?

Answer

The three primary colours of light are Red, Green, and Blue (RGB). When all three primary colours are combined in equal intensity, they produce white light. All other colours can be created by combini

Card 6Secondary and Complementary Colours

Define secondary colours of light and give examples. What are complementary colours?

Answer

Secondary colours are formed by combining any two primary colours: Yellow (Red + Green), Magenta (Red + Blue), and Cyan (Blue + Green). Complementary colours are pairs where a secondary colour combine

Card 7Persistence of Vision

What is persistence of vision? Give two practical examples where this phenomenon is observed.

Answer

Persistence of vision is the phenomenon where the visual experience of an object persists in our eyes for about 1/16 of a second after the object is removed from our field of vision. Examples: 1) A ri

Card 8Electromagnetic Spectrum

What is the electromagnetic spectrum? List the components in order of increasing wavelength.

Answer

The electromagnetic spectrum is the orderly distribution of electromagnetic radiations arranged according to wavelength or frequency. In order of increasing wavelength: Gamma rays, X-rays, Ultraviolet
