//Multiple Choice

What did Isaac Newton's prism experiment demonstrate? {
    ~Light consists of particles
    ~Light is a wave
    =White light is composed of various colors
    ~None of the Above
}

Which of the following colors is not a part of the spectrum produced by a prism in Newton's experiment? {
    ~Red
    ~Green
    =Black
    ~None of the Above
}

In Newton's experiment, he used a second prism to\: {
    ~Further disperse the light
    ~Prove that light is made of only red color
    =Recombine the spectrum into white light
    ~None of the Above
}

The sequence of colors obtained from a prism in Newton’s experiment is called\: {
    =Spectrum
    ~Diffraction pattern
    ~Refraction series
    ~None of the Above
}

Which color of light deviates the least when passing through a prism in Newton's experiment? {
    ~Violet
    ~Green
    =Red
    ~None of the Above
}

//True or False

Newton's experiment proved that white light is a combination of multiple colors. {T}

In Newton's prism experiment, blue light bends more than red light. {T}

Newton used a concave lens in his experiment to split the white light. {F}

In Newton’s experiment, when the second prism is placed in the path of the spectrum, the colors remain separated. {F}

The phenomenon observed in Newton's experiment is due to reflection of light. {F}


//Match the following

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Dispersion -> Splitting of light into colors
=Red light -> Deviates least
=Second prism in Newton's experiment -> Recombination of colors
=Prism -> Optical device for refraction
}
