Chapter 13, Problem 16TE

Complete the following equations:

Yellow light + blue light = _____light.

Green light + _____light = white light.

Magenta light + yellow light + cyan light = _____ light.

Solution

To determine: The suitable words for the blanks given in the statements.

Answer:

Blue light when mix with yellow light gives green light, while green light when mix with magenta gives white light and if magenta, cyan and yellow light are mixed it gives white light.

Explanation:

The Sun emits light of all frequencies and the green-yellow part of the spectrum of the light emitted by it is the brightest and our eyes are more sensitive to this part of the spectrum.

The human eyes have three types of cone cells that detect light of low (red), medium (green), and high (blue) frequencies. If all these three colors are allowed to be stimulated in equal proportion, we have a white perception of this combination.

So, if yellow light and blue light are mixed together, it gives a green light, while green and magenta form white light and magenta, cyan and yellow light gives white light.

Conclusion:

Therefore, blue light when mix with yellow light gives green light, while green light when mix with magenta gives white light and if magenta, cyan and yellow light are mixed it gives white light.
