Question 1:
Which property of light determines its color?
Explanation: The correct answer is A) Wavelength. The property of light that determines its color is its wavelength. Different wavelengths of light correspond to different colors in the visible spectrum, ranging from shorter wavelengths (such as blue and violet) to longer wavelengths (such as red and orange).
Question 2:
Which of the following colors has the shortest wavelength?
Explanation: The correct answer is C) Blue. Among the given options, blue has the shortest wavelength. The visible spectrum ranges from shorter wavelengths (blue and violet) to longer wavelengths (red and orange).
Question 3:
Which three colors are the primary colors in the additive color model?
Explanation: The correct answer is A) Red, green, blue. In the additive color model, red, green, and blue are the primary colors. By combining these three colors in varying intensities, it is possible to create a wide range of colors, including the secondary colors cyan, magenta, and yellow.
Question 4:
Which color is perceived when white light is reflected off a red object?
Explanation: The correct answer is A) Red. When white light, which contains all colors of the visible spectrum, is reflected off a red object, only the red component of the light is reflected back to our eyes. As a result, we perceive the object as red.
Question 5:
What is the phenomenon called when two complementary colors are combined, resulting in the perception of white?
Explanation: The correct answer is C) Color addition. When two complementary colors, such as red and cyan, green and magenta, or blue and yellow, are combined, they result in the perception of white. This phenomenon is known as color addition, and it is based on the additive color mixing principles of the red, green, and blue primary colors.
