Question

A) The spreading effect is called ____________.

b) In a spectrum of colors, which color is deviated most?
c) In a spectrum of colors, which color is deviated least?
d) List all the colors of the rainbow in the order that they occur.
e) A man stands 20 m in front of a large plane mirror. How far must he walk before he is 8 m away from his image?

Answer 1

Dispersion is the effect that spreads white light into a spectrum of colors; violet is deviated the most and red the least in a spectrum. The colors of the rainbow appear in the order of red to violet. To be 8 meters away from his image, a man must walk 4 meters towards a plane mirror.

Step-by-step explanation:

The spreading effect is called dispersion. In the spectrum of colors that make up a rainbow, the color that is deviated the most is violet, while the color that is deviated the least is red. The colors of the rainbow occur in the following order: red, orange, yellow, green, blue, indigo (sometimes listed), and violet. As for the mirror question, since the distance between an object and its image in a plane mirror is double the actual distance to the mirror, the man would need to walk 4 meters to be 8 meters away from his image in the mirror.
