20 points and i will mark as brainliest also

Answer 1

Dispersion of light into seven color.

Answer 2

In the activity of the prism, the formula we have to prove is:
  + A = i1 + i2
where the = angle of deviation
                  A = angle of the prism
                  i1  = angle of incidence
                  i2 = angle of emergence
