Question 1:

Which of the following is not a primary color of light in the additive color model?

A) Red
B) Green
C) Blue
D) Yellow

Show Answer

Explanation: The correct answer is D) Yellow. In the additive color model, the primary colors of light are red, green, and blue. By combining different intensities of these three colors, it is possible to create a wide range of colors, including secondary colors such as yellow, cyan, and magenta.

Question 2:

Which color is associated with the longest wavelength in the visible spectrum?

A) Red
B) Green
C) Blue
D) Violet

Show Answer

Explanation: The correct answer is A) Red. Among the colors in the visible spectrum, red light has the longest wavelength. The visible spectrum ranges from shorter wavelengths (blue and violet) to longer wavelengths (red and orange).

Question 3:

How many primary colors are there in the subtractive color model?

A) 1
B) 2
C) 3
D) 4

Show Answer

Explanation: The correct answer is C) 3. In the subtractive color model, there are three primary colors: cyan, magenta, and yellow. By combining different proportions of these three colors, it is possible to produce a wide range of colors, including the secondary colors red, green, and blue.

Question 4:

What is the range of wavelengths for the visible spectrum of light?

A) 300-700 nm
B) 400-800 nm
C) 500-900 nm
D) 600-1000 nm

Show Answer

Explanation: The correct answer is B) 400-800 nm. The visible spectrum of light encompasses wavelengths ranging from approximately 400 nanometers (nm) to 800 nm. This range of wavelengths corresponds to the colors that humans can perceive, from violet and blue to green, yellow, orange, and red.

Question 5:

Which cone cells in the human eye are primarily responsible for color vision?

A) Rods
B) S cones
C) M cones
D) L cones

Show Answer

Explanation: The correct answer is B) S cones, C) M cones, and D) L cones. Color vision in humans is primarily mediated by threetypes of cone cells in the retina: S cones (short-wavelength), M cones (medium-wavelength), and L cones (long-wavelength). Each type of cone is sensitive to a different range of wavelengths, allowing us to perceive a wide spectrum of colors. These cone cells work together to process and interpret the different wavelengths of light, enabling us to perceive and distinguish various colors.
