In 1897, British physicist J. J. Thomson showed that cathode rays were composed of a negatively charged particle, which was later named the electron.
Explanation :
In Newton's prism experiment, a ray of white sunlight is passed to the prism. It is observed that the light gets refracted at different angles and different colors spread.

- Red
So, the correct option is (c) " White sunlight is made up of all the colors of the visible spectrum ".

The magnitude of displacement =
the distance between start-point and end-point,
regardless of the route followed along the way.
Any motion that ends up where it started has zero displacement.
An object on a circular path starts over at zero displacement every time
it completes a full revolution. So does a race-car on a track.
