Multiple choice newton's colour disc light and the formation of shadows physics

Primary colours of light are:

  1. red, yellow, blue

  2. blue, orange, green

  3. red, blue, green

  4. all colours
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Red, blue and green are known as the three primary colours. Those are often regarded as basic colours in nature. By mixing these colours in different proportions, all other colours may be obtained.

Multiple choice newton's colour disc light and the formation of shadows physics

What are composite colours?

  1. Colours produced by mixing two or more primary colours, in proper proportions.

  2. Colours which combine easily with primary colours

  3. Tertiary colours when mixed in proper proportions

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Red,blue ,green are known as the three primary colours. By mixing these colours in different proportions, we get all other colours. The primary colours, when mixed in proper proportion, give us white light. Any other colour,produced by mixing two or more primary colours, in different proportions, is called a composite colour.

D Correct answer
Explanation

The prism splits the incident white light into a band of 7 colors. The various colors seen in the band are arranged in a particular sequence of Violet, Indigo, Blue, Green, Yellow, Orange and Red (VIBGYOR).

Multiple choice newton's colour disc light and the formation of shadows physics

Sunlight is made up of ____ colors.

  1. 7

  2. 6

  3. 5

  4. 4
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Isaac Newton was the first person to split sunlight into seven colors using a glass prism. When he tried to split the band of colors further using a second prism placed in the inverted position as compared to that of the first, he observed that the emergent ray was white colored. This gave him an idea that sunlight is made up of 7 colors and any other light that gives a spectrum similar to that of sunlight is often referred to as white light.

Multiple choice newton's colour disc light and the formation of shadows physics

The light of one single colour is called:

  1. monochromatic

  2. multichromatic

  3. dichromatic

  4. polychromatic
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Monochrome means single colour. The light of one single colour is monochromatic. White light have seven colours. So it is polychromatic.

Multiple choice newton's colour disc light and the formation of shadows physics

What does Newton's colour disc possess?

  1. 7 segments in rainbow colours

  2. 5 segments in rainbow colours

  3. 4 segments in rainbow colours

  4. 9 segments in rainbow colours
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Newton's colour disc, as the name suggests, was invented by Sir Issac Newton and is a disc with seven segments in rainbow colours.

Hence, the correct answer is OPTION A. 

Multiple choice newton's colour disc light and the formation of shadows physics

Which of the following two colours are complementary colours? 

  1. Red and Gresn

  2. Red and Magenta

  3. Red and Cyan

  4. Yellow and Red
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Red and cyan are complementary colors. When mixed, they produce white light. The other pairs (red-magenta, yellow-red, red-and-green with typo) are not complementary pairs.

Multiple choice physics option a: relativity the nature of light speed of light and optical density introduction to light

All colours travel with the same speed in :

  1. Vaccum

  2. Glass

  3. Water

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In a vacuum, the refractive index is 1 for all frequencies, so all colors (wavelengths) travel at the same speed c. In media like glass or water, dispersion occurs, meaning speed depends on the refractive index, which varies with wavelength.

Multiple choice physics light and shadow substances which allow light to pass through and those which do not transparent, opaque and translucent objects shadows

Name the body which absorbs all colours.

  1. Black

  2. White

  3. Red

  4. Yellow
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Black objects absorb all colours so no light is reflected.

Black really isn't a color. Its the absence of colour. Colours have the colour they do because the named colour is the light colour that they reflect. In other words a red item reflects red light and absorbs all other colours. A blue coloured item reflects blue and absorbs all other colours except blue. So when an item is said to be black, it reflects no colour: therefore all colours are absorbed.
