Suggest an activity to prove that all the colors of the rainbow get mixed up to give white light?
Also, draw a suitable diagram for the activity.
Answers
Explanation:
The refractive indices of the crown glass for blue and red lights are 1.51 and 1.49, respectively, and those of the flint glass are 1.77 and 1.73, respectively. An isosceles prism of angle 6
o
is made of crown glass. A beam of white light is incident at a small angle on this prism. The other flint glass isosceles prism is combined with the crown glass prism such that there is no deviation of the incident light. If the net dispersion of the combined system is

Answer:
The Newton disc experiment
Explanation:
The Newton disc, also known as the disappearing color disc, is a well-known physics experiment with a rotating disc with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo, and violet or ROYGBIV) appearing as white (or off-white or gray) when it spins very fast. This type of mix of light stimuli is called temporal optical mixing.
